➀
3 safety terminals, Ø 4 mm, marked: "+", "G" and "-".
➁
Access to terminal "G" protective fuse.
➂
7-way rotary switch:
 OFF: switches off unit power
 500 V - 2 T  : insulation measurement at 500 V, up to 2 T 
 1000 V - 4 T  : insulation measurement at 1000 V, up to 4 T 
 2500 V - 10 T  : insulation measurement at 2500 V, up to 10 T 
 5000 V - 10 T  : insulation measurement at 5000 V, up to 10 T 
 Var. 50 - 5000 V: insulation measurement with variable test voltage
 SET-UP: adjustment of unit confi guration
➃
1 yellow START / STOP push button: start / stop of measurement.
➄
6 keys (C.A 6545) or 8 keys (C.A 6547) made of elastomer, each having a main function and a
secondary function:
2nd Selection of the second function (in yellow Italics above each key).
R-DAR-PI-DD Primary function: before the insulation measurements, selection of
required measurement type: normal measurement, calculation of dielectric
absorption ratio (DAR), calculation of polarisation index (PI) or Dielectric
Discharge test DD. After or during the measurements, display of R, DAR,
PI, DD and capacitance (µF).
R(t)
Secondary function: display/no display of intermediate values of insulation
resistance, test voltage and time stamp, following a programmed time test
(the V-TIME and
V / TIME Primary function: In insulation, display of elapsed time from the beginning
of measurement, then of exact voltage generated. In MR (memory recall)
mode, display of the date and time of the stored measurement, of the exact
test voltage and of the memory address OBJ:TEST.
Secondary function: activation/deactivation of "programmed time test"
mode.
Primary function: ON/OFF of display backlight.
ALARM Secondary function: activation/deactivation of alarms programmed in
SET-UP.
Primary function: Select a parameter for modifi cation.
SMOOTH
Secondary function: ON/OFF for display smoothing during insulation
measurement .
Primary function: increments the displayed fl ashing parameter. Browse the
list of intermediate insulation results in the R(t) function.
Secondary function: decrements the fl ashing parameter displayed. Browse
the list of intermediate insulation results in the R(t) function.
If the
keys may also be used).
and keys are pressed and held, the parameter changes faster.
