Thank you for buying the ATLAS Charging Scale
and Charging Module!

The ATLAS and its companion Charging Module offer an innovative design in refrigerant
measurement and charging. Use the ATLAS Scale for manual recovery and/or charging
measurement. Or, add the Charging Module to give you a fully automatic charging station.
The Weighing Platform, Control Hand Piece and Charging Module can be replaced at any

ATLAS Refrigerant Charging Scale

The ATLAS scale’s few controls allow for easy operation. See the diagram on the left side
of this page for the location of items on the scale. The following buttons and operating
instructions apply if you are using the Weighing Platform with the Control Hand Piece
instead of the Charging Module.
A Communication Cable: The communication cable connects the Weigh Platform and the
Control Hand Piece. Insert an end of the cable into each component. Ensure the cable is
secure by listening for a “click” when attaching the cable.
B Battery Compartment: The ATLAS operates on a 9 volt alkaline battery. Install the
battery by sliding open the access door in the back of the control hand piece and snapping
it onto the connector.
C ON/OFF Switch: Press the button once to either turn the ATLAS on. Depress the button
for one second to turn the ATLAS off. When turned on, the ATLAS will perform an
initialization test.
D Unit Selection: The ATLAS will display weight measurements in decimal pounds
(XXX.XX lbs), pounds and ounces (XXX lbs XX.XX oz) or kilograms (XXX.XX kg). Push this
button to toggle between units.
E Tare (Zero): This button allows you to manually zero the ATLAS at any time during
operation. NOTE: When first turned on, the ATLAS will automatically zero.
F Display: Indicates how much weight has been placed on or taken off the Weigh Platform.
The display will show positive and negative values. If the scale goes over its weight limit,
the display will say “Over Range”. When the battery becomes low the display will say “Low
Battery” (steady at first but flashing when the scale is about to shut off). When the battery
power is too low to provide an accurate reading, only “Change Battery” will show on the
display. If the scale cannot auto zero because maximum weight is exceeded during
initialization, the message “Over Range - Remove Weight” will be displayed.
Auto Shut Off: To extend battery life, the ATLAS Scale will shut off in 30 minutes. When
restarted after an auto shut off, the ATLAS will perform its initialization test and
automatically zero. There is a provision in the ATLAS software to disable the auto shut off
feature. Contact JB Industries for instructions

ATLAS Charging Module

The ATLAS Charging Module will allow you to turn your ATLAS scale into an automatic
charging station. The Charging Module is acceptable to use with all refrigerants and blends.
The following instructions describe how to use the scale with its companion charging

Identification of Parts

A: Power Connection: Socket for the AC/DC power adapter. The Charging Module
requires an AC/DC adapter; use only an adapter supplied by JB Industries. A power
adapter is included with the Charging Module.
Note: When the weighing platform is used with the Charging Module, the auto-shut off

function is disabled.

B: Display: The LCD display on the charging module has two lines. The bottom line
displays the programmed charge amount and messages, when applicable. The top line
displays the actual weight as measured by the weighing platform.
C: On/Off button: Turns the ATLAS Charging Module on or off. Depress the button for one
second to turn the Charging Module off.
D: kg/lb button: Toggles the Charging Module’s units of measure. Available units of
measure are kilograms, decimal pounds and pound/ounces.
E: Tare/Clear button: This button is represented by a “

∅ “ and it “zeros”, or tares, the

weight reading displayed when depressed quickly. It also clears the programmed charge
amount when depressed and held for one second. NOTE: When the scale and Charging
Module are first powered on, the scale will automatically tare, even if there is weight on the
weighing platform.
F: Charge/Hold button: Starts or pauses (holds) the charging operation.

G: Right Arrow button: Allows you to move between digit positions when programming a
charge amount.
H: Up Arrow button: When programming a refrigerant charge amount, this button allows
you to increase the number in the highlighted digit position of the display, as selected with
the right arrow button.
I: ATLAS Connector: The communication cable which connects the charging module to
the weighing platform plugs into this connector.
J: “Out” Fitting: Connects the charging module to the system being charged with
refrigerant (or manifold gauge set). The size of the fitting is ¼” refrigeration flare fitting.
K: “In” Fitting: A ¼” refrigeration flare fitting for connecting the charging module to the
refrigerant cylinder, using a refrigerant charging hose.

Charging Module Setup and Operation

Setting up the Charging Module

1. Place the ATLAS weighing platform on a firm, level surface.
2. Connect the communication cable to the Charging Module and the ATLAS weighing

platform. Plug the AC/DC power adapter into the Charging Module and then into its
power supply.

3. Turn on the charging module by depressing the On/Off button.
4. Place the refrigerant cylinder on the weighing platform.
5. Connect a refrigerant hose from the refrigerant cylinder to the fitting marked “In” on the

Charging Module. Connect another refrigerant hose from the fitting marked “Out” on the
charging module to the system being charged with refrigerant.


Prior to making the second hose connection, it may be necessary to purge the
hoses of air with a small amount of refrigerant. This can be done by programming
the Charging Module for a quantity of 1 oz. and initiating the charge function (See
Charging Module Operation).

6. You may wish to put a manifold gauge set between the Charging Module and the system

being charged. In this case, connect the hose from the fitting marked “Out” on the
charging module to the center port on the manifold gauge set. Connect the manifold set
to the system to be charged.

Charging Module Operation

Once the Charging Module has been set up as described above, it is ready for operation.
1. Press and hold the Tare/Clear button for one second. This will clear the last programmed

target charge. You will hear a short beep to signal that the charge is cleared.

2. Program the desired charge amount on the bottom line of the Charging Module’s display

using the Up Arrow and Right Arrow buttons. Press the Right Arrow button to position the
flashing cursor on the digit to be changed. Press the Up Arrow to increase the number in
the position of the flashing cursor. If the Up Arrow button is depressed and held, the
number will increase rapidly until the button is released. If the digit reaches “9”, press the
Up Arrow again to return the flashing digit to zero.
The smallest charge increments available are 10 gm (when in kg units), .01 lb (when in
decimal pound units) and .25 oz (when in lbs/oz units).

3. Ensure the valve on the refrigerant cylinder is open.
4. Start the charging operation by pressing the Charge/Hold button. You will hear the

internal solenoid valve click open and refrigerant will flow. The display will flash “CHRG”
on the bottom line of the LCD display next to the programmed target charge amount. The
top line of the display will zero when the Charge/Hold button is pressed and will show the
actual amount of refrigerant transferred as refrigerant flows through the Charging
Module. When the programmed target charge amount is reached, the solenoid will close,
you will hear two short beeps, and the display will alternately flash “Charge Complete”
and the programmed target charge amount.

How to put the Charging Operation on Hold

Once the charging operation has begun, you can pause it at any time by pressing the
Charge/Hold button once. The solenoid valve will close, stopping the refrigerant flow, and
you will hear one short beep. The display will flash “HOLD” and the programmed target
charge amount on the bottom line of the display. Press the Charge/Hold button again when
you are ready to resume charging.

How to put the Charging Operation on Hold and use the ATLAS
and Charging Module in Scale Mode

If you need to measure a refrigerant cylinder while the charging operation is on hold, you
can easily put the scale and charging module into weight scale mode temporarily. After you
have put the Charging Operation on Hold, press the Tare/Clear button once. This will put
the unit into weight scale mode. The top line of the display will show the weight based on
the last time the scale was zeroed. Place the new tank on the weighing platform and its
actual weight will be displayed. If you wish, press the Tare button again to zero the scale to
the weight. When you are ready, press the Charge/Hold button to resume charging from the
amount already transferred. You will hear one short beep when charging resumes.

How to Perform Repeated Charges of the Same Amount

The last programmed target charge amount will be automatically saved in the Charging
Module’s memory. If you would like to repeat the same charge amount, simply press the
Charge/Hold button once again to start a new charging cycle using the previously
programmed target charge amount.
