Instrument Measurement
CAUTION! Risk of injury and material damage!
Any voltage higher than 30 V will lead to possible personal injury and damage to the de-
vice.
Never apply more than 30 V between any two terminals, or between any terminal and
ground.
CAUTION! Material damage!
Exceeding the measuring range will cause possible damage to the device.
Do not apply a voltage exceeding the measuring range to the input terminal.
CAUTION! Material damage!
Any connection with a device without cutting off its power supply will cause possible
damage to the device.
When connecting to the device, the power supply of the device under test should be
cut off.
CAUTION! Material damage!
Pay particular attention not to connect the current signal to the input terminal. Incorrect
connection may cause damage to the instrument and the device under test.

Measuring resistance and thermal resistance (RTD)
1. Make sure that INTPUT is indicated on the display. If not, press the Output/Input button.
2. Press the FUNC button to select the resistance or thermal resistance (RTD) function.
3. Press the 4/3/2W button to select the number of wires.
4. Insert one end of the test lead into the OUTPUT terminal of the instrument and connect
the other end to the input terminal of the device under test. See Figure 6-1, 6-2 and 6-3.
