6-8 Calibration

NetScan User’s Manual

Gain Calibration of Main Unit

Required Equipment*

- Volts DC Calibrator
- 22-2 Twisted pairs (to connect calibrator to calibration card)
- Digital Voltmeter, or Digital Multimeter

(used for verification of calibration voltages)

- Calibration Card (installed in bottom slot, slot #1, of main unit)

see required specifications on page 6-2

&$87,21

Offset calibration of main unit must be completed prior to calibrating the main unit for
gain.

&$87,21

Use approved ESD precautions, including static-free work area and grounded wrist strap,

when handling circuit boards and electronic components. Failure to do so could cause
equipment damage due to electrostatic discharge.
