Key

When programming the alarm thresholds, the key can be used
to scroll through all the possible values of the flashing elements
and then loop back to the beginning:
MΩ or GΩ for insulation, kΩ or Ω for resistance, for the
measurement units,
1,2, 3 or _ for the thousands digit,
0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 for the hundreds, tens and units,
"-.- - -" or "- -.- -" or "- - -.-" or "- - - -" for the decimal separator,
> or < for the upper or lower threshold.
When programming the capacitance per unit length in nF/km,
the key can be used to change the values of the flashing
digits to 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.
2.3.5 Key
1039 and 1035
When this key is pressed, the backlighting of the display comes
on. It will be turned off automatically one minute later. When it is
lit, you can turn the backlighting off by pressing this key again.
1039
When the switch is on 4000 nF, a long press on this key enables
you to program the unit length value (see 4.7).
2.3 ∆REL key
A long press on this key enables you to memorize a value.
The measurements that follow will be the positive or negative
deviation compared with the value memorized (does not function
for voltage on the MΩ positions).

3. MEASUREMENT FUNCTIONS

3.1

Insulation

The insulation measurements correspond to the MΩ positions
of the switch.

3.1.1 AC / DC voltage measurement

As soon as the switch is set to one of the MΩ positions, the
instrument measures the voltage between its + and - terminals.
The value of this voltage is displayed (0 to 600 V AC / DC max.).
If the voltage present is less than 25 V, the insulation can be
tested, but the lower the test voltage the greater the possibility
of error.
If the voltage is greater than 25 V, "
Pressing the yellow key does not trigger insulation measurement,
but causes a series of buzzes (buzz, buzz, buzz, ...) and makes
the symbol flash until the yellow key is released.
> 25 V " is displayed.
