DISPLAY

MEANING

RELAY 2

The status relay LED flashes when the respective set
point value has been reached. Indication is only for
the standard, internal set points.

GROSS/NET

Indicates the mode of the measured value on the
display. All calibration should be done in Gross
mode.

TOTAL/ROC

Indicates the mode of operation currently PEAK
configured.

NOTE:

Total, Rate-of-change, and Peak are options that must be installed before these led
indicators will function.

Lb/Kg

Indicates U.S. or metric unit-of-measure of the
weight parameter on the display.

Bar Graph

The Bar Graph function displays in graphical form
the value of the mode (Total, Gross, Net, ROC,
Peak) selected in the bar graph setup menu.

NOTE:

The bar graph mode and the display mode are totally independent. Make sure you
know what mode each are in before reading.

Load Check

Step 1.

Place a load (weight) on the scale or vessel.

Step 2.

Check to see if the weight reading changes on the display in
the proper direction.

e.g. if the display reads 100 pounds and a 20 pound load is
placed on the vessel or scale, the display should read 120
or some value over 100.

If the display reads 80 pounds and a 20 pound load is
placed on the vessel or scale, the reading is going in the
wrong direction and indicates a problem. (See the Chapter
8, Troubleshooting for corrective action.)

If the display is reading improperly or shows no change,
something is wrong either with the setup or configuration.

Step 3.

If the display changes in the proper direction, remove the
weight and proceed to calibrate the controller.

Calibration Setup
Procedures

The Calibration Menu

NOTE:

When calibrating the instrument for the first time, go from one sub-menu to the next in
sequence. If you want to change one of the sub-menus, continue to press the Up Arrow
button until you reach the sub-menu you want to change.

NOTE:

After entering a value in each sub-menu the display will flash a GOOD if the value is
accepted. If the value is not accepted the display will flash an ERR # statement.
