7 Calibration Services

Calibration certificates – DKD-certificates – other certificates: If device should be certificated for its accuracy,
it is the best solution to return it with the referring sensors to the manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get results of highest accuracy!

8 Specification

Measuring ranges:

Display range:

max. -19999...19999 digit, depending on connected sensor

Resolution:

depending on connected sensor

Pressure units:

mbar, bar, kPa, MPa, mmHg, PSI, mH

2

O

selectable depending on connected sensor

Accuracy: (typ.)

±0,1%FS  

(at nominal temperature)

(FASt and P.dET:  ±0.5%FS)

Measuring rate:

slow:

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

fast:

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

Nominal temperature:

25°C

Sensor:

All sensors of the GMSD and GMXD..-series without recalibration can be connected

Connection: 

Mini-DIN-Socket with locking mechanism
The sensor will automatically be detected, the measurement range settings are set
referring to sensor data

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 values can be monitored constantly 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

Logger:

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

Memory: 

Stor: 99 data sets; CYCL: 10000 data sets

Cycle time CYCL:

1...3600 seconds (= 1h)

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

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).

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: < 1.6 mA
Fast measuring rate: < 7.0 mA
Low-Power-Logger: < 0.3 mA  (for cycle time>30s, without interface
communication active and no alarm horn sounding) up to 0.8 mA (at cycle time 1s)

Housing

impact-resistant ABS, membrane keyboard, transparent panel, Front side IP65

Dimensions: 

142 x 71 x 26 mm (L x W x D)

Working conditions:

-25 ... +50°C,  0 ... 95 %RH (non condensing)

Storage temperature:

-25 ... +70°C

EMC

:

The device corresponds to the essential protection ratings established in the
Regulations of the Council for the Approximation of Legislation for the member
countries regarding electromagnetic compatibility (2004/108/EG).
Additional fault: 

<1%
