fast:
>1000 meas./sec (ConF-Rate = FASt and P.dEt)
Nominal temperature:
25°C
Sensor:
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)
Logger:
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
