on, it is set to the temperature scale that was in use
when the thermometer was last turned off. To change
the temperature scale, press the “°C/°F” key

“ ” Display Back-Light

Press the “ ” key to turn on or turn off the Back-Light.

“T1 T2/T1-T2” Main display Input Selection

The input selection indicates which input is selected
for main display; T1 probe, T2 probe or the difference
between the two probes (T1-T2). When the thermometer
is turned on, it is set to T1, when main display input
selected T1, then T1 input can select alternate of probe
by pressing Pt385/Pt3926/Pt3916 key switch.

“TYPE”(Pt385/Pt3926/Pt3916) Main display Input
RTD Probe Select

The “TYPE” key switches the T1 input to select the Pt385,
Pt3926 or Pt3916 RTD probe as input, when main display
input selected T1. When the thermometer is turned on,
it is set to the probe selected that was in use when the
thermometer was last turned off.

“MAX/MIN” With Time Record Mode
(only Main display)

Press “MAX/MIN” key to enter the MAX MIN Recording
mode, (displays the Maximum reading with time,
Minimum reading with time and Average reading stored
in record mode). In the this mode the automatic power-

off feature is disabled and “ ” key, “°C/°F” key, “REL”
key, “SET” key, “Hi/Lo LIMITS” key and main display
“T1 T2 T1- T2” key, “TYPE” key are disabled. The beeper
emits a tone when a new minimum or maximum value
is recorded.
Press “MAX/MIN” key to cycle through the MAX, MIN
and AVG readings. If an overload is recorded, the
averaging function is stopped. In this mode, press the
“HOLD” key to stop the recording of readings, all values
are held, press again to restart recording.
To prevent accidental loss of MAX, MIN and AVG data,
this mode can only be cancelled by pressing and holding
the “MAX/MIN” key for 2 seconds. All recorded readings
are erased.

“REL” Relative Mode (only Main display)

Press the “REL” key to enter the relative mode, zero the
display, and store the displayed Reading as a reference
value. REL is shown on the display. Press “REL” key
again to exit the relative mode. The relative reference
value can also be entered by the user. (See “SET mode”
later in this manual). When the desired relative value
has been entered, press “REL” key to enter the relative
mode and than press “SET” key use the entered relative
value as a reference value. Press “REL” key again to exit
the relative mode. In the relative mode, the value (can
not >±1999.9 counts) shown on the LCD is always the
difference between the stored reference and the present
reading.

“HOLD” Mode (only Main display)

Press the “HOLD” key to enter the Data Hold mode, the
“HOLD” annunciator is displayed. When HOLD mode
