Calibration
25-2
There are four columns on the Calibration dialog box: Measurement Point, Measured Value,
A/D Counts, and Calibration Factor.
Measurement Point – Allows selection of input channels when calibrating. Usually, the
parameters selected never need to be changed. The Measurement Point also serves as a diagnostic
tool that can lock in on a channel for troubleshooting.
Measured Value – Type measured values in this column. The MPM uses only Temperature 1;
the BDS uses two temperature channels per DCM.
A/D Counts – The value from the A/D (Analog to Digital) converter before any calibration
(Calibration Factor) is applied. Also referred to as Raw Counts.
Calibration Factor – The correction factor required to obtain a value that can be displayed on
the String View screen.
Scan / Edit is a toggle action button. Clicking Edit allows editing of the Calibration Factors.
Clicking Scan disables editing. Clicking a Measured Value field displays A/D counts.
Required Test Equipment:
4-1/2 digit DVM – Fluke 87 or equivalent.
100 millivolt and 10 millivolt source.
