1 Set the rotary switch to
2 Connect the red (+) and black
(–) test leads to the INPUT
terminals.
3 Probe the resistor (or shunt)
leads and read the display.

1 Set the slide switch to the M
position to disable the output.
2 Set the rotary switch to mV.
3 Press and hold
than 1 second.
4 Plug the thermocouple probe
(with adapter) into the INPUT
terminals.
5 Touch the surface to be
measured with the
thermocouple probe and read
the display.
Disconnect circuit power and discharge all high-voltage capacitors before measuring
resistance to prevent possible damage to the instrument or the device under test.
.
• Before measuring the temperature of a circuit or device, disconnect its power.
• The bead type thermocouple probe is suitable for measuring temperature from
–40 °C to 204 °C in PTFE compatible environments. The probes may emit toxic
gas above this temperature range.

For continuity test, the instrument will
beep if the resistance is less than the
values indicated below:

Best practices:
• Do not bend the thermocouple
leads at sharp angles.
Repeated bending may break
the leads.
• Do not immerse the
thermocouple probe in any
liquid.
• Clean the surface to be
measured and make sure that
the probe is securely touching
the surface.
