A REC Relative clock is active for recording min and max
temperature occurences or for time stamp purposes.
B MAX/MIN Maximum or minimum temperature
measurements are being monitored.
C HOLD/REL Freezes primary display or establishes a relative
zero for the primary display information.
D BAT Low battery indicator.
E °C °F Displays temperature in either degrees Celsius or
degrees Fahrenheit.
F T1-T2 Toggles screen information from T1 (Primary)/ T 2
(Secondary) to T2 (Primary) / T1 (Secondary) ,then to T 1-T 2
(Differential) on Primary and alternating T1/T2 temperatures
on Secondary display.
G Primary data display. Displays T1, T2, or T1-T2( temperature
differential -TD ) or a relative zero of T1, T2, or TD.
H KJTRSE Selects proper input reference for thermocouple in
use. T1 and T2 must be the same thermocouple type.
I Secondary data display. Displays T2,T1 or T1 and T2
temperatures.
J Thermocouple input. Positive and negative polarized plugs for
the thermocouple probes used ( Blade type ); T1 on the
left,T2 on the right.
K Relative clock display. Displays time in hours, minutes, and
seconds (HHMMSS) when REC is pressed and the relative
time that MIN or MAX data was recorded.
L RS-232 output port. Optional software and cable – PN
TM-SWA.
M AC to DC converter input.
