Test Procedure Conditions
These procedures are valid only under the following conditions:
H
The system has been calibrated at an ambient temperature of 23
_ ±
5
_
C.
H
The system is operating in an environment whose limits are described in
Table 4--6 on page 4--5.
H
The system, including probe, has had a warm-up period of at least
20 minutes.
H
The probe degauss/autobalance routine has been performed after the
20-minute warm-up period.
Equipment Preparation
Before performing the verification tests, turn all equipment on and allow the
entire system to warm up for a minimum of 20 minutes.
NOTE
. Before performing any verification procedure, properly degauss the
probe. Remove the probe from any current-carrying conductor, lock the probe,
and press the amplifier PROBE DEGAUSS AUTOBALANCE button. The
degauss/autobalance routine is complete when the indicator light turns green.
The amplifier front panel will light the NOT TERMINATED INTO 50
Ω
LED
during the degauss/ autobalance routine if the amplifier is not properly
terminated into 50
Ω
. Verify that the oscilloscope input is 50
Ω
and set to DC
coupling. Use a 50
Ω
feedthrough termination, attached at the oscilloscope
input, if necessary.
