287/289 Users Manual Measuring Temperature XW Warning To avoid the potential for fire or electric shock, do not connect the thermocouple to electrically live circuits. The Meter uses an 80BK-A Integrated DMM Temperature Probe or other type-K temperature probe for measuring temperature. To measure temperature, set up the Meter as shown in Figure 14. Press the softkey labeled Menu and move the menu selector to the menu item labeled Temp. Press the softkey labeled F for temperature in Fahrenheit or C for Celsius. Note A Meter classified as "SI" will not have an F selection. The primary display normally shows temperature or the message "Open Thermocouple". The open thermocouple message may be due to a broken (open) probe or because no probe is installed into the input jacks of the Meter. Shorting the W terminal to the COM terminal will display the temperature at the Meter terminals. Note R is disabled when the Meter is in the Temperature function. 28 8:10pm 06/13/07 26.5 C Menu +8.0 Offset Save Offset Setup 80BK Type K Thermocouple Probe Vent or Pipe est17.eps Figure 14.

Measuring Temperature
XW
Warning
To avoid the potential for fire or electric shock, do
not connect the thermocouple to electrically live
circuits.
The Meter uses an 80BK-A Integrated DMM Temperature Probe
or other type-K temperature probe for measuring temperature.
To measure temperature, set up the Meter as shown in
Figure 14. Press the softkey labeled
Menu
and move the menu
selector to the menu item labeled
Temp
. Press the softkey
labeled
F
for temperature in Fahrenheit or
C
for Celsius.

The primary display normally shows temperature or the message
“Open Thermocouple”. The open thermocouple message may be
due to a broken (open) probe or because no probe is installed
into the input jacks of the Meter. Shorting the

terminal to
the
COM
terminal will display the temperature at the Meter
terminals.
