2.
Assemble the calibration kit as described in the Calibration section of this insert.
NOTE:
Do not screw the regulator into the calibration cylinder at this time.
3.
Set a voltmeter to measure in the millivolt (mV) range.
4.
Remove the junction box cover, then plug the voltmeter leads into the test points on
the amplifier.
Plug the positive lead into the test point labeled
TP+
; plug the negative lead into the
test point labeled
TP-
.
5.
Use the following formula to determine the correct test points output for the test
sample.
Output (mV) = (calibrating sample/fullscale) X 400 + 100
For example, with a test sample of 50 PPM CO and a fullscale setting of
300 PPM, the correct output is 167 mV.
167 (mV) = (50/300) X 400 +100
Entering the Calibrate program
1.
Open the Pioneer’s housing door, and locate the program buttons to the right of the
