4 Technical Description
4.3 Cold-start Delay
Serves to suppress false measurements while the probe warms up to operating temperature.
Cold-start delay is always activated after POWER OFF and probe replacement.
The cold-start delay can be aborted at any time
• via the multifunction key
• via the optional display and operating unit, see separate publication
• via Remote-Display-Software, see separate publication
During the cold-start delay, either
• a substitute value (factory setting), O
2
0 % vol. (P361)
• set the type of the substitute value for O
2
in P362:
OFF: No output of the substitute value
ON: Output of the substitute value of the preceding parameter.
+Maintenance: (factory setting): Output of the substitute value of the preceding parameter,
even in maintenance mode.
+Maint.freeze: Output of the substitute value of the preceding parameter in the case of cold
start or error as hitherto. Additionally the preceding measurement value is freezed, as long as
maintenance mode is active.
The substitute value during cold start/error takes priority over the freezing of the measurement
value during maintenance.frozen
After a pre-heating period of 10 minutes the probe voltage stabilises to a value between
0 ... 20 mV and the AC inner resistance to a value below 100 .
