Temperature Probe Setup {rtd}
The temperature measurement function can be set to use a two wire
{2W}
or four wire
{4W}
connection - the latter using the
SENSE
sockets in addition to the
HI
and
LO INPUT
sockets.
The default value is four wire
{4 W}
.

The instrument can be returned to factory defaults. This will return all values to their defaults
and clear any stored data.
When
[OK]

{ACCEPt}
.
The reset is performed when

Switch Off on AC Power disconnection {AC OFF}
The action of the instrument when AC power is disconnected can be changed. Three options
are available: Normal
{OFF}
,
Auto
{AUtO}
or Battery
{bAtt}
.
For the default condition, AC OFF set to Normal
{OFF}
, the instrument is restored to its
previous state prior to power down (on or standby) when AC power is applied and turned off
when the AC power is disconnected.
There are situations where the instrument should remain on (operating under battery power)
when the AC power is disconnected, e.g. when logging readings over an extended period; for
these, the Auto or Battery settings will be more appropriate.
With AC OFF set to Auto
{AUtO}
,
the instrument is restored to its previous state prior to power
down (on or standby) when AC power is applied but the action when AC power is disconnected
depends upon how the instrument was turned on. If the instrument was turned on by
connection of AC power, removing the AC power will turn it off (as in the default condition).
However, if the instrument was turned on from battery power, removing the AC power will not
turn it off.
With AC OFF set to Battery
{bAtt}
,
connecting or disconnecting the AC power does not turn the
instrument on or off.
