INSTRUMENT POWER

3.3.1 MAINS POWER
The kit includes a power cable for connection to the mains supply.
Make sure that mains power is 230VAC ± 10% 50/60 Hz (or 110VAC ± 10% 50/60 Hz if your version is designed for
this rating).
Simply plug the mains cable into the socket at the rear of the instrument (see Fig. 3.1) and into the mains power outlet.

Set the I/O switch to I to switch the instrument on.
The I/O switch only affects the instrument's low tension circuits and battery output circuits (practically speaking, with
the switch set to I, the instrument operates normally; with the switch set to O, the instrument control circuits are
switched off but the battery charging circuit remains on).
With the instrument switched on, you can make the measuring connections required.
3.3.2 BATTERY POWER
The MICROVIP3 PLUS can also work by its internal rechargeable battery. The instrument automatically switches to
battery power as soon as the mains cable is disconnected.
The MICROVIP3 PLUS uses a Ni-Cd 6V 940 mAh battery (with five 1,2 V 940 mAh elements in series) giving the
instrument an autonomy of over seven hours providing no printouts are required and the display backlight is switched
off (the display backlight can be activated by pushing the button on the rear panel, and switches off after approximately
15 seconds from the moment the button is released).
Do not use battery power for long measuring operations or when extensive printing is needed.
The instrument warns of low battery level by displaying three flashing dots on the calendar-clock display. When battery
power is low, the instrument automatically disables the print function (see figure).
PRG SELC SETC
To restore printer functions, connect the instrument to the mains power at least until the third dot goes out (15 minutes
approx.).
If the battery is completely drained, for example after a long period in storage, the instrument may not switch on at all.
If it happens, simply connect the instrument to the mains to recharge the battery.
Leave the instrument switched off (standby) and connected to the mains for 24 hours to fully charge the battery.
IMPORTANT: no ground connection is needed when the instrument is working by battery:
DO NOT CONNECT THE INSTRUMENT TO GROUND.
