7. Battery Installation and Replacement
(1) Turn the battery slot cover clockwise and remove it.
(2) Remove the used battery (CR2032) from the slot.
(3) Insert a new battery in the slot. Make sure the positive (+) side is facing up.
(4) Put the cover on the slot and turn it counter-clockwise.
Note:
When the battery mark
goes off, immediately replace the battery with a new one. Using the
thermometer while the battery mark
is not displayed may affect the measurement accuracy
and cause malfunctions.
CAUTIONS
- If the thermometer is not going to be used for a long time, always remove the battery to prevent it from
self-discharging or leaking fluid.
- Although the label by the slot for the backup battery states "Battery for Laser", the PC-8400
Ⅱ
does not
have a laser. This slot should be used to store a backup battery.
- The life of the battery set in a unit at shipment may be shorter.
8. Measurement
(1) Press the Scan key to start measuring: Pressing the Scan key turns on the unit.
(2) Release the Scan key to cancel measuring: Releasing the Scan key turns off
the unit after approximately 15 seconds, displaying "OFF."
(Automatic power-off function)
(3) With the PC-8400
Ⅱ
, the ratio of D (the distance to the object) to S (the diameter of the measurement
spot on the object) is 6: 1. For details, see "Notes on Measurement"
CAUTIONS
- Do not use the PC-8400
Ⅱ
near a microwave oven. If used in a strong electromagnetic field, readings may
be inaccurate or unstable.
- The default set of the emissivity is 0.95. If the emissivity of the object to be measured is other than 0.95, be
sure to change the emissivity as described in "Emissivity Setting Function." Otherwise, accurate readings
will not be obtained.
- Do not get too close to an object whose surface is hot during measuring, otherwise you may burn yourself
by accidentally touching the object or by its radiant heat.
- Upon power-on, a value other than the measured value may be displayed instantly. This is not a
fault.
