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 I to 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 (Q on 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.
