SELECTING THE PROBE TYPE

To prevent measurement errors, ensure that your test tool is adapted to your probe at power-on. Note that the PM8918 probes, delivered with the test tool, have an attenuation of 10:1.

For accurate measurement, periodic probe calibrations are necessary. This is explained in Chapter 8, "User Mainte- nance".

WARNING

To prevent electric shock and personal injury, Mini Test Hooks and HF Adapters must not be connected to any voltage higher than 42V peak (30V rms) to earth. Always pay attention to the markings on the accessories.

POWER-ON CONFIGURATIONS

There are two different ways to reset the ScopeMeter test tool: the Master Reset, and the power-on/save memory.

Master Reset (Default Startup)

CAUTION

A Master Reset clears everything saved in memory. Never perform a Master Reset unless you are prepared to lose everything you saved in memory.

1.Turn the ScopeMeter test tool off.

2.Press and hold .

3.Press and release .

The test tool turns on, and you should hear a double beep, indicating the Master Reset was successful. The screen should display input: A PROBE 10:1 on top of the waveform area.

4.Release .

Perform a Master Reset only to make sure that your test tool is in the initial settings condition. Master Reset sets the test tool for using 10:1 probes.

See Chapter 6 for more information about Master Reset conditions.
