(display ‚m‘)

, selectable

Accuracy: (typ.)

±0,2%FS (hysteresis and linearity)
±0,4%FS (temperature dependency 0-50°C)

OPTION higher accuracy: 

±0.1%FS (hysteresis and linearity)
±0.4%FS (temperature dependency 0-50°C)

Measuring rate:

slow:

4 meas./sec (ConF-Rate = Slow)

fast:

>1000 meas./sec (ConF-Rate = FASt and P.dEt)

Nominal temperature:

25°C

Piezo-resistive relative pressure sensor integrated in device.
Suitable for air and non-corrosive and non-ionizing gases and liquids.
(Not suitable for water – use air buffering)

Connection: 

2 metal pressure ports for connection to 6 x 1 mm tubes at the top of device (4mm
inner tube Ø)

2 Functions: individual value logger („Func–Stor“) and cyclic logger („Func–CYCL“)

Memory: 

Stor:  99 data sets
CYCL: 10000 data sets (in max. 64 recording sequences)

Cycle time CYCL:

1...3600 seconds

Display:

2 four digit LCDs (12.4mm high and 7 mm high) for measuring values, and for min/
max memories, hold function, etc. as well as additional functional arrows.

Pushbuttons: 

6 membrane keys

Output:

3.5 mm audio plug, stereo

Output function:

selectable as serial interface or analog output

Interface:

Serial interface (3.5mm jack) can be connected to RS232 or USB interface of a PC
via electrically isolated interface adapter GRS3100, GRS3105 or USB3100 (see
accessories).

Analog output:

0 ... 1 Volt, freely scaleable (resolution 12 bit)

Power supply: 

9V battery, type: IEC 6F22  (included in scope of supply)
as well as additional d.c. connector (diameter of internal pin 1.9 mm) for external
10.5-12V direct voltage supply.             (suitable power supply: GNG10/3000)

Power consumption: 

Slow measuring rate: ~ 0.6 mA
Fast measuring rate: < 2.5 mA
Low-Power-Logger: < 0.1 mA  (for cycle time>30s, without interface
communication active and no alarm horn sounding) up to 0.4 mA (at cycle time 1s)

Low battery warning:

' bAt '

Additional Functions:
Power-Off-Function: 

Device will be automatically switched off if no key is pressed/no interface
communication takes place for the time of the power-off delay. The power-off delay
can be set to values between 1 and 120 min.; it can be completely deactivated.

Min/Max-Alarm:

The measuring value is constantly monitored for the min and max rails set.
Alarming is done by integrated horn, display and interface

Real time clock:

Integrated clock with date and year
