Measuring Low Resistance
To measure low resistance:
1. Zero out the test lead resistance (see Table 1).
2. Connect the probes to the circuit to be measured.
If voltage is present on the probes, the voltage is displayed.

Warning
A repetitive beep and the flashing high voltage
symbol (
Y
) warn the user if voltage more than 30 V ac
or dc is present. If the voltage is > 30 V ac or dc,
remove the voltage from the circuit under test before
proceeding with the next step.

3. Press and hold the TEST button. A single beep indicates a stable reading. The
resistance shows on the main display. If the resistance is higher than 40 Ω, >40 Ω is
displayed.
4. Release the TEST button. The upper right display holds the resistance reading until a
new test is started or a different function is selected.
