Function; Alarm keeps turning on until potential causes of a problem are eliminated.
Type; Oxygen concentration alarm,
alarm, EMF stabilization time-up alarm, Cold junction temperature alarm, Thermocouple voltage alarm,
Input current alarm, Battery low alarm, Input-pressure alarm, Cell resistance alarm
NAMUR NE 107 Alarm Display Function: Displays 4 warnings of NAMUR NE 107 standard;
F: Failure (Fault equivalent, Power supply to the heater shuts down.)
C: Function Check
S: Out of Specification
M: Maintenance Required
Data Logging Function: Stores following data to SD card or visualizes on the instrument display. SD
cards which are recommended or equivalent must be supplied by customer,
Event display; Log of Alarms, Calibration Trend, Power-on history are displayed on the main unit.
Graph Display; Displays trends of test result of resistivity from a cell resistance tester
SD card output; Measurement log (date/time, oxygen concentration, cell e.m.f, test result from a
cell resistance tester, cell condition, NE107 status, etc.) Maintenance report (setup value,
calibration value etc.) can be saved to SD cards in CSV format. The stored data can be
copied to other converter by outputting user-setting parameters to SD cards.
Sensor Self-diagnosis Function:
Calibration mode diagnose; Span/Zero compensation rate, cell response time, cell condition
Cell resistance test ; result from a cell resistance test without feeding calibration gas
• Measurement mode; auto cell resistance test, semi-auto cell resistance test,
• Cell resistance test setting; stabilization time (min. sec.) starting time (year/month/date/
hour/minute) measurement interval (day/time)
