2.3 Power
supply
MicroCal P200
can be powered from:
internal rechargeable Ni-MH battery.
External battery charger, supplied as a standard accessory (the batteries must be installed).
The Ni-MH rechargeable batteries allows a long time operation and do not need maintenance. The same batteries power both the instrument and the external pressure modules.
Battery life (typical):
10 h on Tc and mV input/output (backlight Off)
4 h with 20 mA simulation (backlight Off)
Recharging time (typical): 5 h at 90% and 6 h at 99% with instrument switched off.
During operation a fully battery symbol “
≠
” will be displayed on the display. This symbol means that the batteries are completely full. When the batteries will be discharged the
symbol “
–
” will appear and the instrument still has about 20 minutes operation capability to end the running analysis.
The battery symbol indicates that a full charge is required. Use only the dedicated battery charger supplied by Eurotron together the instrument.

2.4 Electrical
connections
MicroCal P200
calibrator is designed to be insensitive to transients or noise, the following recommendations should be followed to reduce ac pick up in the signal leads and to
ensure a good performance. The input leads should not be run near ac line wiring, transformers and heating elements. Input/output leads should, if possible, be twisted and
shielded with the shield grounded at the end of the cable. When shielded cables are used the shield must be connected to the negative terminal.
The following figure shows some examples of input/output wiring of the instrument:
