Calibration
Your DAS-1800 Series board is initially calibrated at the factory. You are
advised to check the calibration of a board every six months and to
calibrate again when necessary. This section provides the information you
need to calibrate a DAS-1800 Series board.
Equipment Requirements
The equipment requirements for calibrating a DAS-1800HC Series board
are as follows:
●
A digital voltmeter accurate to 6
½
digits, such as a Keithley
Instruments Model 196 or 2001
●
An adjustable ±10V voltage calibrator, such as a Keithley
Instruments Model 236
●
A CAB-1800 Series cable and a STA-1800HC, STP-100, or
CONN-1800HC, or a user-designed interface
Potentiometers and Test Points
Figure 6-1 shows the locations of the potentiometers and test points
involved with the calibration of a DAS-1800HC Series board. The
potentiometers are labeled R5 to R8, R12 and R13, R15 and R16, and
R20. The test points are TP1 to TP5. The calibration utility, described in
the next section, directs you to these components and explains what to do
with them during the calibration process.
