T1/T2 -
T Button:
Pressing the T1/T2 -
T Button selects in sequence T1, T2 and
T.
T is the
temperature difference T2- T1.
The actual measurement T1, T2, T2-T1 is displayed in the upper left hand corner of the
LCD.
OPERATING INSTRUCTIONS
OPERATION
1. Connect the K-type thermocouples to the instrument input.
2. Put the thermocouples near or on the sample tested.
3. Slide the function switch to the appropriate range or, if in doubt, select the highest
setting (1°). If the measured temperature is below 200
, the higher resolution range 0.1
can be selected, if needed.
4. The Model CA863 may be in degrees Celsius (°C) at power-up. Press the back-light
button
for more than 2 seconds to toggle over into degrees Fahrenheit (°F), if
desired. The selected setting will remain for the next use.
5. Thermocouples need a certain time to respond. Take the reading when the
measurement has stabilized.
6. The HOLD button will freeze the measurement in the display, and will not update until
released.
7. When finished, remove the thermocouple from the sample, unplug the thermocouple
from the meter and slide the switch to OFF.
