CALIBRATION
ADJUSTMENT PROCEDURE
5-21
M19/20
10:1 calibration
for channei A (red) and channei B (grey)
probes
Purpose: determine the
gain, using a 10:1 probe.
Calibration equipment:
Red scope probe (delivered
with the ScopeMeter)
Qrey scope probe (delivered
with the ScopeMeter)
Red adjust
adapter (delivered with the ScopeMeter)
Calibration
setup:
IMPORTANT: Calibration steps M19
and M20 determine the Internal calibration constants that
compensate for
probe cheractenstics. To achieve full
accuracy (a$ listed In the
specifications in chapter
2)t
calibrations Ml 9 and M20 must be performed,
using
the probes that are normally
to be used with the instrument.
If the probes delivered with the
ScopeMeter are not available at the time of
calibration, use other probes
specifically designed for the ScopeMeter. In
this
case you must notify the
user that these calibrations have been performed,
using different probes.
To achieve full accuracy, the user must
do a User Probe
Calibration, using his own probes. This
procedure Is described in the
ScopeMeter Users Manual.
Because the results of these User Probe Calibrations
