5. TEMPERATURE MEASUREMENT
5.1 Correct Measurement Method:
The temperature sensor is located at the end
of the metal sheath of the sheath type
TEMPERATURE PROBE. To accurately test
internal temperature insert the probe into the
item you want to measure to a distance at
least 15 times the diameter of the sheath.

When the AC adapter is used, insert the plugs of the adapter into the DC9V connector on the side
panel.
Note:
When
the AC adapter is connected while battery is inserted, the unit will be powered from
the
adapter (the AC adapter has priority).
