Performing a zero point adjustment
1. Operate the system until operating conditions have settled.
2. Stop the flow (v = 0 m/s).
3. Check the shut-off valves for leaks.
4. Check that operating pressure is correct.
5. Using the local display, select the zero point adjustment function in the function matrix:
PROCESS PARAMETER
→
ZERO POINT ADJUST
6. When you press
O
or
S
you are automatically prompted to enter the access code if the
function matrix is still disabled. Enter the code (factory setting = 65).
7. Use
O
or
S
to select START and press
F
to confirm. Select YES at the prompt SURE? and press
F
again to confirm. Zero point adjustment now starts.
– The message # 561 “ZERO-ADJ. RUN” appears on the display while adjustment is in
progress.
!
Note!
– If the flow in the pipe is unstable, the following error message may appear on the display
# 451 “ZERO-ADJ. N. OK”. The Zero point adjustment is not OK. The preconditions need
to be stabilized before attempting a new adjustment.
8. Back to the HOME position:
– Press and hold down Esc key (
X
) for longer than three seconds or
– Repeatedly press and release the Esc key (
X
).
Resetting a zero point adjustment
The currently stored zero point can be reset to the original factory value by using the RESET option
within ZERO POINT ADJUST function.
Use
O
or
S
to select RESET and press
F
to confirm. Select YES at the prompt SURE? and press
F
again to confirm. The zero point adjustment is now reset.
6.9 Data storage device (HistoROM)
At Hauser, the term HistoROM refers to various types of data storage modules on which
process and measuring device data are stored. By plugging and unplugging such modules, device
configurations can be duplicated onto other measuring devices to cite just one example.
6.9.1 HistoROM/S-DAT (sensor-DAT)
The S-DAT is an exchangeable data storage device in which all sensor relevant parameters are
stored, i.e., pipe type, diameter, serial number, flow conditoner, zero point.
6.9.2 HistoROM/T-DAT (transmitter-DAT)
The T-DAT is an exchangeable data storage device in which all transmitter parameters and settings
are stored.
Storing of specific parameter settings from the EEPROM to the T-DAT and vice versa has to be
carried out by the user (= manual save function). Detailed instructions regarding this can be found
in the handbook “Description of Device Functions” (function T-DAT SAVE/LOAD).
