d. Take a reading of the actual sensor output signal.
e. Wait 100 seconds, and take another reading.
value = (reading 1 – reading 2) / 100 seconds
f. Calculate the resulting value and then compare the resulting value to the
expected value:

–0.545 to +0.545 mV/s
Glu I, Glu A –5.348 to +5.348 nA
Lac I, Lac A –5.348 to +5.348 nA
g. Press Stop Test .
CAUTION:
Touch the inner surface of the module frame to discharge static
buildup before removing or returning sensors.
6. Reinstall the sensors:
a. Open the measurement module door.
b. Remove the test/blank sensor.
