General
Power:
Battery 9V or ac/dc adapter 12 V with NiMH accumulator 9V
_____________________________________________________________________________________________________________________________________________________________
If instrument is supplied from external ac/dc adapter, internal 9V battery should be replaced with rechargeable
NiMH accumulator. In usual operation from adapter accumulator is charged only with small current.
If accumulator is totally discharged, its full charging in instrument takes approximately 100 hours. Instrument
with accumulator is not recommended for permanent operation without ac/dc adapter plugged. Accumulator
works only as a standby source in case of power mains failure.
Average current consumption:
0.3 to 1.3 mA (depending on operation mode)
_____________________________________________________________________________________________________________________________________________________________
Battery life depends on selected display refresh mode (see below). In FAST mode display is refreshed in
shortest possible interval with highest current consumption. In dynamic mode display is refreshed in interval
up to 5 s in case measured values remain stable. Refresh interval is shortened to approximately 0.7 s only
if measured values change. Current consumption in this mode in usual operation is lower, battery life is up to
4 times longer. The FAST mode is recommend to use only in cases, when slower display response is not
acceptable.
Battery voltage drop below 7 V is indicated with blinking of "BAT" in default display mode (displaying of actual
values) and FAST mode is automatically cancelled to save the battery. At the same time audio indication of
alarms is automatically switched OFF.
Measuring interval and display reading refresh approximately:
0.7 s
in FAST mode
0.7 to 5 s
in dynamic mode
Interval of refresh of pressure tendency display:
0.5 h
Display:
Backlit two-line LCD
