| "on" |
visual alarm via display,
interface alarm, alarm sound via integrated signal-horn |
| "no.So." |
visual alarm via display
and interface alarm |
|
controlling function: |
by means
of the switching module GAM 3000 (optionally against surcharge)
electric equipment can be switched on/off or alarm memorized |
|
real-time clock: |
clock with date and year integrated in the device |
| SeaLevel-correction: |
when connecting
an absolute pressure probe the barometer air pressure can also be
indicated adjusted
to sea level "zero". (air pressure improvement by entering the meters
above sea level "zero") |
Only ONE portable device for a all kinds of pressure and for any measurement ranges, with additional functions compared with GMH 3110 (logging function, alarm function, real-time clock...)
