RANGE key
. AUTO mode to switch to MANUAL mode (short press).
. MANUAL mode, to select the next range (short press) or return to AUTO mode (long
press).
Measurements concerned: voltages (except 500 mV range), capacitance, resistance,
current (except 10 A range).
. When making time measurement (frequency, duty cycle) : if the range change made
during previous measurements (Voltage or Current) was in manual mode, it may be
necessary to adapt this measurement range to the signal level injected at the input. This
is why the RANGE key is used to change from one range (Voltage or Current) to the
next range. The new range is then displayed for 2 seconds.

REL key
Short press : REL mode, the last value measured becomes the reference value derived
Long press :

Pk +/- key
The fast positive or negative peak measurement functions ( ≥ 1 msec.) can be accessed by
repeatedly pressing this key in the V

MEM key
Short press :

Autostore
Set the probes on the point to be measured. An audio signal indicates if the measurement is
stable. When you remove the probes, a second audible signal indicates that this stable
value displayed has been stored.

ZOOM key
You can press this key to expand the bargraph readout five times for positive measurements
and eleven times for bipolar measurements, one centred around zero (centre zero mode).
Adjusts ohm-value references in dB and audio power measurements.
When the current measurement is dB or audio power, you can display the resistance
reference with the ZOOM key (long press). This value can then be adjusted using the SEL
and RANGE keys. You quit the ohm reference adjustment mode with the ZOOM key (short
press).
Benchtop multimeter
from subsequent measurements. In temperature measurement the REL key
used to compensate the connexions resistance (see § 4.1.7.)
When in REL mode, a long press displays the reference being used. This
value may be adjusted using the SEL key (selection of digits and a
sign) and the RANGE key (increment the selected digit).
Fixes the display on the current value.
Accesses or quits the "autostore" mode. Can be accessed in the V
