ADJUSTMENT
To obtain the best performance, periodically calibrate the
unit. Sometimes, only one mode need be calibrated, while
at other times, all modes should be calibrated. When one
mode is calibrated, it must be noted that the other modes
may be affected. When calibrating all modes, perform the
calibration in the specified sequence.
The following calibration required an accurate measuring in-
strument and an insulated adjusting flat blade screwdriver.
If they are not available, contact your dealer. For optimum
adjustment, turn the power on and warm up the scope suffi-
ciently (more than 30 minutes) before starting.
Before calibrating the unit, check the power supply voltage.
