Output signal hold:
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.
Valve and Flow meter (option):
Selects zero or span gas during manual
zero or span calibration. Mounted on the
side of the converter.
Communication function:
RS485 (MODBUS) (option)
Combustion efficiency display (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.
