Precise Low-Current Measurement

Warning
W
To avoid electrical shock and injury:
• Do not hold the meter anywhere beyond the tactile barrier.
• Do not use the meter to measure currents above the maximum rated
frequency (400Hz). Circulating currents may cause the magnetic circuits
of the jaws to reach hazardous excessive temperatures.
Voltage can be measured at the same time by using the V/COM terminals
while the jaws are measuring current. Lower display shows voltage
measurement. Also see Measuring AC and DC Voltage section.
To measure AC low-current for small conductors:
1. Turn the rotary switch to any function to power
on the meter. The default current measurement
mode is AC A (upper display). Press
to switch between AC A and Amp-Tip mode (
displayed).
2. Open the clamp by pressing the jaw release and
insert the conductor to be measured into the clamp.
Ensure the jaws are firmly closed.
3. Align the conductor at the specified jaw tip area for
low-current measurement (Amp-Tip).
4. View the current reading on the upper display.

Caution
During current measurement keep the jaws away from
other current-carrying devices such as transformers,
motors or energized wires, as they may negatively
influence accuracy of the measurement.

HVAC flame sensor testing.
To test a heating system flame sensor:
1. Turn the heating unit off and locate the wire
between the gas-burner controller and the flame
sensor.
2. Disconnect one of the flame sensor wires.
3. Turn the rotary switch on the meter to
4. Connect the black test lead to the COM terminal
and the red test lead to the μA terminal.
5. Connecting the meter in series by attaching one
test lead to the disconnected flame sensor probe
and the other test lead to the disconnected control-
module terminal.
6. Turn heating unit on and check the reading on the
Meter.
