The table below shows the listing of the resistances requested for verification, the measurement current levels,
and the 95x specification at each resistance value and current level. When prompted for each step the user should
either
–
•
Press
START
to perform the verification.
•
Press
STOP
to abort the entire sequence.
During each step, the user should note the displayed resistance measurement on the 95x display and record it,
checking against the 95x specification shown in the table below. When the user is satisfied that the step has been
completed, the user should press
START
to continue or
STOP
to abort the sequence.

OPTION HSS CURRENT VERIFICATION
This series of steps is only included if option HSS is fitted.
The first step in this series requires no external equipment, all 95x terminals should be disconnected. For the
remaining steps in this series the user should connect the prompted value resistance (equipment #8 in the
equipment list above) between the
HV
terminal of the 95x and the HI terminal of the milli-ammeter. The LO
terminal of the milli-ammeter should be connected to the RETURN terminal of the 95x. The milli-ammeter is used
to determine the actual load current, the 95x displays the value which it is measuring.
The table below shows the listing of the resistances requested for verification, the measurement current levels,
and the 95x specification at each current level. When prompted for each step the user should either
–
•
Press
START
to perform the verification.
•
Press
STOP
to abort the entire sequence.
During each step, the user should note the displayed measurement on the 95x display and record the difference
between this measurement and the milli-ammeter reading, checking against the 95x specification shown in the
table below. When the user is satisfied that the step has been completed, the user should press
START
to continue
or
STOP
to abort the sequence.

OPTION HSS-2 CURRENT VERIFICATION
This series of steps is only included if option HSS-2 is fitted.
The first step in this series requires no external equipment, all 95x terminals should be disconnected. For the
remaining steps in this series the user should connect the prompted value resistance (equipment #9 in the
equipment list above) between the
HV
terminal of the 95x and the HI terminal of the micro-ammeter. The LO
terminal of the micro-ammeter should be connected to the RETURN terminal of the 95x. The micro-ammeter is
used to determine the actual load current, the 95x displays the value which it is measuring.
