After the supply voltage has been applied, the printing recorder will be initial-
ised and is then in the basic status. Measurements are made, processed, and
recorded.
The 24-character LED dot-matrix display can show:
- instrument designation (name), date and time
(the time can be switched off via the parameter Parameter level
time)
- channel number and measurements (incl. units) of all active channels
(in pairs)
- channel number, name and measurement (incl. units) of all active channels
(sequentially)
- status and error messages
- interface texts
v Section 10.6 "Interface (RS422/RS485)"
- customer-specific texts
The display can be either cyclic or static:
Cyclic display
The printing recorder switches automatically to the next display after about
3sec.
Static display
In the basic status, the static display is activated and de-activated with E.
If it is activated, then the present display remains, and is regularly updated.
In the basic status, the information in the display can be changed over with the
h and R keys.
Status and error messages will be identified in plain language by a regularly
flashing display, instead of the present display.
The display of status and error messages can be inhibited, or activated again,
by pressing l + r .
If a measurement is outside the valid range of the A/D converter
(out-of-range), or if a probe break has been detected, then the
character combination ">>>>>>" will appear in place of the value.
The recording can be stopped or re-started with the S key. In the stop status
"STOP" will flash in the LED dot-matrix display.
Using the e key, in the stop status, activates the chart fast-forward.
Pressing the F key for at least 4 sec will restart the scaling print-out.
The operating level can be accessed by pressing the h + R keys simultane-
ously.
