Operating Instructions; Monitoring Temperatures In Real Time - General DT8852 Manual Del Usuario

DT8852 and DT8856 users: If you insert only one thermocouple into
the T1 or T2 port, the readout corresponding to the unused port will
show four dashes (see figure below).

OPERATING INSTRUCTIONS

MONITORING TEMPERATURE(S) IN REAL TIME
To measure temperatures sensed by installed thermocouples, press
the button to power on the unit. The T1 temperature will appear on
the primary readout (all three models). The T2 temperature (DT8852
and DT8856 only) will appear on the secondary readout. This is the
"normal" display mode.
To swap the readouts (so T1 is shown on the secondary readout and
T2 is shown on the primary readout), press the CHANNEL button once
(DT8852 and DT8856 only). This is the "swap" display mode.
To show T1-T2 on the primary readout and alternating temperatures
T1 and T2 on the secondary readout, press the CHANNEL button again
(DT8852 and DT8856 only). This is the "T1-T2" display mode.
To resume showing T1 on the primary readout and T2 on the
secondary readout, press the CHANNEL button again (DT8852 and
DT8856 only).
When the thermometer is powered on, it will resume operation in the
same Channel mode—normal, swap, or T1-T2—that it was in when it
was powered off.
To hold a T1 reading ("freeze" the primary readout), briefly press the
REL/HOLD button. While the T1 reading is held, the T2 reading will
continue to be updated on the secondary readout (DT8852 and
DT8856 only). To release the hold and resume showing real-time
T1 values on the primary readout, briefly press the REL/HOLD button
again.
On the single-input DT8855, the button at the lower left of the front
panel is labeled TIMER, rather than CHANNEL. Pressing the TIMER
button starts a running clock with 1-second resolution in the lower
