MAX/MIN mode

For each measurement function, this mode displays three values in the form of True RMS:

Minimum recorded value of the measurement,

Average of all recorded measurements,

Maximum recorded value of the measurement.
Prerequisite: the duration of the record must exceed 100 ms.
If the measured signal drops below the current minimum value or exceeds maximum value, the
readings will be updated to the value of this signal. The meter records also date, time and the period
after which it recorded these values.
Using the function:

Use the rotary switch to select the desired measuring function

Press MAX/MIN button

use F1 F2 F3 F4 buttons to select one of the options:


HOLD function

This function is used to 'freeze' the measurement result on the display.
Using the function:

to activate, press HOLD button,

to save the result use F1 F2 F3 F4 buttons to select SAVE,

to turn off, press HOLD button or select CLOSE.
The activity of the function is signalled by message HOLD. Then, the upper bar of the display
shows the current measured signal.
An additional mode of the function is AutoHold. It monitors the input signal and updates the "fro-
zen" read-out, when the meter detects a new stable value of the signal (such that variations for at
least 1 s. do not exceed the setpoint – sec. 7.7.3).
In addition, the meter detects open measurement circuit. This allows user to plug the meter into a
different circuit, without losing the current reading from the screen.
Using the function:

to activate, use F1 F2 F3 F4 buttons and select AUTOHOLD,

to save the result use F1 F2 F3 F4 buttons to select SAVE,

to turn off, select CLOSE or CANCEL.
