4.1.6. 5 mA / 50 mA / 500 mA / 10 A positions
4.2. 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.
4.3. REL
key
Short press
:
Mode REL, the last value measured becomes the reference value derived
from subsequent measurements.
Long press :
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).
