VOLTAGE CHECK: The tester first checks for possible interference. If there

is an external voltage of more than 42V, the warning triangle

displayed. If measurements are being performed in AUTO mode and a

disturbance frequency is detected, the tester will automatically look for a

frequency that is different from the default 128Hz.

Available in all functions except mΩ and 2 Clamp.

If necessary, the test voltages can be switched to either 16 or 32V as follows:

• Press the Hz/OPTIONS button, then press it again to make the output volt-

age (Uout) blink.

• Use the ► button to switch to 16 or 32V, then press Hz/OPTIONS again.

This setting is retained when the unit is turned off.
