Pyromation Dual J-T-E-K - Manual (Page 16)

OPERATING PROCEDURES
The unit will always power up with the upper dis-
play showing T1 unless T1 is not connected. If
only T2 is connected at power up, the upper dis-
play shows T2 and the lower left display indicates
T1 is open. If thermocouples are not connected to
T1 or T2 at power up, the upper display indicates
an open T1 and the lower right display indicates an
open T2.
If you are in single probe mode and the probe is
moved to the other connector or to restore the dual
probe mode, turn power OFF then back ON.
For optimum operation, allow about one minute for
ambient temperature stabilization. If the unit has
been stored at an extreme ambient condition, more
time may be needed.
BASIC TEMPERATURE MEASUREMENTS
Check that the thermometer is turned on, the
probe(s) connected, the desired resolution 0.1° or
1° is selected, and the desired scale °C or °F, is
selected.
Single Probe Measurements
The thermometer will automatically determine if T1
or T2 connection is being used.
Initially the upper display will indicate the measured
temperature and the annunciator will indicate which
probe is making the measurement. One of the lower
displays will indicate open and the annunciator will
indicate which probe is open. Pressing the T1/T2
key will cause the thermometer to go into the single
probe differential mode described later.
Temperatures > 999.9° have a resolution of 1° and
therefore no decimal will be present.
