7.4.2 Measuring mode
The measured components are output on the display together
with their values and the units in mg/m
3
, vpm or volume per-
cent. With a change in the analyzer status, the corresponding
letter appears in the last two columns ("P" in the example; see
also Display and control panel (Page 91)). The analyzer re-
mains in measuring mode until an AUTOCAL (automatic, re-
mote-controlled or manual) is carried out or until you manually
switch the analyzer to input mode.
If analyzers are installed in closed analysis cabinets, opening
the cabinet door may result in brief drifting of the measured
values. This is a result of the temperature exchange which then
takes place.
If '*****" is displayed in measuring mode without a fault being
present, this means:
•
Concentration in sample gas more than 5% higher than the
largest measuring range
• Signal saturation resulting from excessively high sample gas
concentrations
7.4.3 Input mode
In input mode, you can view instrument parameters or calibrate and parameterize the
analyzer.
CAUTION
Unauthorized operation
The analyzer must only be calibrated and/or parameterized by trained specialists with
adherence to these operating instructions.
Once you have selected input mode, the first menu to appear is
the main menu which displays four menu items. You can use
these to select the individual input functions of the
ULTRAMAT 23:
Analyzer status
With these functions you can call submenus which provide information on the analyzer
status, e.g. entries in the logbook, diagnostics data, and factory data (see Diagnostics
(Page 103) for menu structure).
