RANGE key

• In AUTO mode to switch to MANUAL mode (short press).
• In MANUAL mode, to select the next range (short press) or return to AUTO mode (long
press).
Measurements concerned : AC or DC voltages, capacitance, resistance.
• When making time measurement : if the range change made during previous
measurements (voltage) 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) to the next range. The new range is
then displayed for 2 seconds.

REL key

Short press : Mode REL, 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
A functions.
DC
Portable digital multimeter
DC current measurement
AC current measurement
AC+DC current measurement
from subsequent measurements.
When in REL mode, a long press displays the reference being used. This
value may be adjusted using the SEL/ON key (selection of digits and a
sign) and the RANGE key (increment the selected digit).
