d. Linearization
Linearization is only performed when the
sensor is changed. See section 4-3 be-
low.
e. Measurement Display Configuration
Figure 3-20. Measurement Display Configuration
The “Signal on mini-bargraph” lines are
used to set various status values that can
display on the four lines available on the
single component (Measure) display. Se- lect a line and press the ↵ key. To change
the value use the ↑ and ↓ keys. The val-
ues will scroll through the allowable se-
lections as follows:
Electrolyte level Displays “OK” or “Low.”
Range Displays the range number from 1 to 4.
Sample flow Displays the sample flow rate in ml/min with a bargraph.
Sensor current Displays the sensor current in uA with a bargraph.
Temp. current Displays the heater current in uA with a bargraph.
Sensor temp. Displays the sensor temperature in °C with a bargraph.
Validity Not functional on the TO2.
Operation status Not functional on the TO2.
Move the cursor to the “Measurement display
configuration…” line and press the
↵ key.
The “Measurement Display Configuration”
menu will be displayed.
The first two lines allow for setting the con-
