1. For access to allow the high voltage
warning threshold to be altered,
press the VOLTAGE LIMIT
screen key on the 'Present Settings'
screen
High Voltage Warnings —
Warning and Interlock
1. In the interests of safety, to avoid
electric shock, the 9100
incorporates a high-voltage warning
and interlock system for both DC
and AC Voltage functions. The
limit can be set to any voltage from
10V to 110V. The default warning
threshold value (100V) can be
changed in Configuration mode.
The active threshold value is stored
in non-volatile memory.
2. When the output is on in DCV or
ACV function, the warning will
sound when the output voltage
setting is raised to or above the
threshold value. The output will
not change from its previous value
until the user confirms the new
voltage by re-pressing the OUTPUT
ON button.
2. This transfers to a configuration
screen designed for changing the
'Voltage Limit'. In our
representation, the default value is
shown
3. Use Digit edit or Direct edit to set
the required high voltage warning
limit. If using Direct edit, after
typing the value press the ↵ key on
the keypad (the Direct edit 'V'
screen key in the right-hand
column will perform the same
action).
The 'DEFAULT 100V' screen key
on the right can be used if 100V is
the required level.
4. Press the EXIT screen key to return
to the 'Present settings' menu
screen. The new high voltage
threshold value appears on the
'Present Settings' list.
Note: Out-of-Range Indication
The valid range of limit values is from
10V to 110V. When values outside
this range are entered, an error message
will appear on the screen, and the
'EXIT' screen key label will be
replaced by 'OK'. By pressing 'OK'
the original value is reinstated and the
message disappears, for a second
attempt.
