1.Test Equipment Required
The following test equipment is required for calibration
and servicing of the Model LTC-905. The suggested
specifications are the minimum necessary for proper calib-
ration of this instrument.
Test Equipment Minimum Spec,
oMultimeter Accuracy <±1^
oOscilloscope lOmV sensitivity
1MHz band width
2. Calibration Procedure
»Calibration should be performed after a30 minute warm-up
period. It should also be confirmed that the unit is
connected to the rated power line voltage.
*All adjustment should be completed in the given order,
because some adjustments interact with others.
