Output signal is held during calibration,
processing recoverable sensor, process-
ing diagnosis of sensor, warm-up, PID
auto tuning, under set up maintenance
mode "available" and blowdown. The
hold function can also be released.
Selects zero or span gas during manual
zero or span calibration. Mounted on the
side of the converter.
RS485 (MODBUS) (option)
When you select this display, "rich mode
display" will be simultaneously displayed.
This function calculates and displays
combustion efficiency from oxygen
concentration and measured gas tem-
perature.
Thermocouple (R) is required for tem-
perature measurement.
