WARNING
Do not connect more than 10 A DC current across the 10 A input
terminal or the protection fuse will be tripped.
3. Resistance Measurements
The meter’s resistance ranges, Ω , are 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ,
2 MΩ, 20 MΩ, 200 MΩ. Turn the rotary switch to the proper range.
Follow these steps to make a measurement:
1. Connect the black test lead to the COM input. Note that
the measurement voltage polarity is positive on COM
input.
2. Connect the red test lead to the VΩH input.
3. Probe with the test leads to the DUT and record the
measured reading on display.

WARNING
Do not apply more than 1000 V DC across the terminals or they will
be damaged.
Tips for resistance measuring:
z
The measured value of a resistor in a circuit is often different
from the resistor’s rated value. This is because the meter’s
test current flows through all possible paths between the
probe tips.

In order to ensure the best accuracy in measurement of low
resistance, short the test leads before measurement and note
