to the desired function from off.
RS232C PC computer interface capabilities
The instrument is equipped with an optical isolated data output port at the back case
near the battery compartment. An optional PC interface kit RS232 KiT2 (optical Adapter
Back, RS232 Cable and Amprobe Download Suite) is required to connect the meter to PC
computer thru RS232C protocol.
To enable the RS-232 output, press-and-hold the hz button while sliding the function-
selector to a function.
The lCD displays ’
‘ to confirm activation after the hz button is released.
To disable the RS-232 output, slide the function-selector to any other position.
AutoVA tM Measurement (see figures 5)
Select the AutoVA position.
with no input, the meter displays “Auto” when it is ready.
if no ACA current input via the jaws and a voltage signal > 2.4 Vdc or 30 Vac (40 hz to
500 hz) is present, the meter will display the voltage value with annunciator.
if no voltage signal is present on ‘+” CoM terminals and a ACA current signal > 1 ACA
(40 hz to 500 hz) is present, the meter will display the current value and ~ A.
The Auto-VA feature stays at the auto-select function as long as its signal remains
above the specified threshold.
Press the SeleCT button momentarily to manually step thru the functions (ACA → ACV
→ DCV → Auto-VA).
Resistance Measurement (See fig. 6)
Select the ‘ Ω ‘ function .
insert the test leads into the jacks. The red lead into V/Ω jack, and black lead into CoM
jack.
Remove power from the circuit being tested and discharge all the capacitors.
Connect the test leads to the circuit, the resistance measured will be displayed.
if ol appears on the highest range, the resistance is too large to be measured.
Continuity test (See fig. 6)
Select the ‘�' function.
insert the test leads into the jacks, the red lead into V/Ω jack, and black lead into CoM
jack.
Remove power from the circuit being tested and discharge all the capacitors.
Connect the test leads to the circuit,
The resistance will be displayed and the buzzer sounds when the resistance value is
between 10 and 300 Ω.
temperature Measurement (see figure 7)
Select the °C/°f position.
Press SeleCT button to toggle between °C and °f measurement functions.
insert the banana-plug type-K temperature bead probe noting correct polarity.
