Operation as analogue output: Connection via suitable cable.
Attention: The output mode has to be configured (p.r.t. 2.8) and
influences battery life!
2. Connection
for
pressure sensors
of the GMSD and GMXD-family
3.
The
mains socket
is located at the left side of the instrument
1.4 Display
Units:
an arrow points to the
chosen measuring unit
SL:
appears if sea-level-
correction is activated
Tara:
appears if tara-function
is activated
main display:
shows measuring value
secondary display:
shows min-, max- or hold value
Logg:
appears, if a logger function is chosen
1.5 Basic Operation
When switching on
the device and the logger function is not off the time of the integrated clock will shortly
be displayed. Furthermore the kind of measuring is displayed (Slo/Fast/P.det, p.r.t 2.1) and "Corr", if a
Sensor with activated offset or scale correction is connected.
After changing the battery
the clock-setting menu is activated automatically (‚CLOC‘). Check the clock and
adjust, if necessary (p.r.t. chapter 2).
On-/Off-Switch
Tara:
Calling of tara function
min/max:
Showing the min- resp. max-memory
Store/Quit:
Calling of hold function resp. calling of logger functions (p.r.t. chapter 3)
Set/Menu:
Calling of configuration
Tare Function:
By pressing ´Tara´ (key 3) the displays will be set to 0. All measurings from then on will be
displayed relatively to the set tare values. When the tare function is activated, the arrow
"Tara" appears in the display. To deactivate tare function press ´Tara´ for >2 seconds.
Please Note: Activating/deactivating tara clears the max- & min-memories.
Max Memory:
Pressing ´max´ (key 2) shows the maximum of the measured value. Pressing it again
hides them. To clear the max. memory press key ´max´ for >2 seconds.
Min Memory:
Pressing ´min´ (key 5) shows the minimum of the measured value. Pressing it again hides
them. To clear the min. memory press key ´min´ for >2 seconds.
Hold Function:
By pressing ´Store/Quit´ (key 6) the last measuring value will be held in the secondary
display. Pressing it again hides it. (only when logger = ‚off‘).
Zero-Point Adjustment:
If there is no pressure or zero-pressure (absolute) applied to the pressure ports the
device will display 0. If there is a permanent deviation (and device is operated under
steady conditions), a permanent zero point adjustment can be carried out. To carry out the
adjustment press button 3 for approx. 5 seconds (Auto Null will be displayed shortly). The
adjustment is done via the OFFSET-value of the sensor (referring configuration menu).
Please note: A zero-point adjustment can only be carried out if the difference between the
value on display is less than 500 digits!
To recall the manufacturer’s calibration press button 3 for approx. 15 seconds.
Note: If a zero-point adjustment was carried out, this will be signalled by the short
displaying of „Corr“ when switching on the device.
