AC Channel
Calibration
Process
To calibrate a channel ( Main Menu>Utilities>Analog Input Calibration) :
1. Select the channel or channels from the list. More than one channel of volt-
age or current can be chosen using the Control/Shift + left-click .
2. Enter the voltage or current magnitude that is applied to the channel. The sig-
nal magnitude level should be measured with a precision calibrated instru-
ment.
3. Press the Calibrate Offset and Gain button. If a channel has not yet been con-
figured, only Calibrate Offset will be displayed.
4. Under the Offset and Gain columns the line of the channel being calibrated
OK or No will be displayed (see “Analog Input Calibration” on page 7-11).
5. Repeat for all other channels being used.
6. Use the
Save button to load the new calibration to the recorder.
Out of Range
An error message is displayed if the applied signal as seen by the recorder dif-
fers from the value entered in the Applied Signal
field by more than 10%. This
helps to prevent erroneous calibration.
It is possible to calibrate multiple channels simultaneously by using
the mouse to select a set of channels from the list. Multiple channels
can be selected using standard Windows selection methods.
