Measuring Electrical Parameters

Using TouchHold

Note

You must have MIN MAX recording off to use TouchHold.

!Warning

To avoid possible electric shock, do not use TouchHold to determine if dangerous voltage is present. TouchHold will not capture unstable or noisy readings.

Activate TouchHold® if you want the meter to freeze the display on each new stable reading (except in the frequency counter function). Press Ito activate TouchHold. This feature allows you to take measurements in situations in which it is difficult to look at the display. The meter beeps and updates the display with each new stable reading.

Compensating for Test Lead Resistance

Use the relative reading feature (Qon the display) to set the present measurement as a relative zero. A common use for this is to compensate for test lead resistance when measuring Ω.

Select the Ω measure function, touch the test leads together, then press C. Until you press C again, or switch to another measurement or source function, the readings on the display will subtract the lead resistance.
