3.8.3 Recording the Before Calibration Readings
To simplify taking before-calibration readings, first clear the Cellcorder
memory. To erase the strings, at the Main Menu, press F1. (Refer to Erasing
String Data in
Memory Management
.) Record the before-calibration (as-
found) readings onto a photocopy copy of the Calibration Log.
The values of the 2 volt, 6 volt, and 12 volt sources or cells used in the
following tests are approximate. Actual values may vary by a nominal
amount.
3.8.3.1 Cell
Readings
1) Select Multimeter mode on the Cellcorder so the actual voltage is
being read.
2) Connect a 2V cell to the Cellcorder using the standard (two lead)
voltage leads supplied with the Cellcorder.
3) Measure the voltage using the HP 5 ½ digit voltmeter (or equiv).
4) Record the value on the Calibration Log under Cell 2V: Actual
Input.
5) Measure the voltage using the Cellcorder.
6) Record the value under the Cell 2V: Before Calibration.
7) Connect a 6V source to the Cellcorder using the standard leads.
8) Measure the voltage using the HP voltmeter.
9) Record the value under Cell 6V: Actual Input.
10) Measure the voltage using the Cellcorder.
11) Record the value under the Cell 6V: Before Calibration.
12) Connect a 12V to the Cellcorder using the standard leads.
13) Measure the voltage using the HP voltmeter.
14) Record the value under Cell 12V: Actual Input.
15) Measure the voltage using the Cellcorder.
16) Record the value under the Cell 12V: Before Calibration.
