4.5 Cleaning the Sensor
First, confirm that the high voltage is turned off. Then align the front end of the cleaning device
with the cleaning port, and slowly insert the cleaning device with the sponge side facing down.
The cleaning device must be inserted up to the scale line indicated on the back side of the cleaning
device. When the scale line is flush with the port, stop and wait for approximately 20 seconds.
Then, insert the cleaning device further, and pull it out from the other side. The sensor will then be
drying, and a flashing “WAIT” message will be displayed on the screen. Approximately 3 minutes
is required for drying. When the sensor is dried, the “WAIT” message will stop flashing. The bar
indicator of the measurable range should return to the initial position. If the indicator is not
returned to its initial position, the above cleaning process must be repeated again as there may be
dust remaining on the senor.
Caution:
1) Ensure that the high voltage is turned off before cleaning the sensor.
Residual high voltage is not fully discharged right after power off. Before starting cleaning,
confirm that the pointer of the high voltage indicator is at the left end of the display.
2) When the sensor is cleaned, the flashing “WAIT” message will be displayed. During this
period, high voltage cannot be supplied even if the [MEAS] is pressed. This is not a
malfunction. When the sensor is dried, the “WAIT” message will stop flashing. Excess
moisture on the cleaning device could lead to a prolonged drying time. If it is taking a long
time for the sensor to dry, absorb the moisture on the sponge with a folded tissue or paper
towel and repeat the cleaning procedure with the drier sponge.
3) Do not force the cleaning device in if the sponge is torn or protruding from the cleaning
device. Forcing the cleaning device could apply excessive pressure to the sensor causing
damage.
4) Using a dirty sponge could prevent the measurable range indicator from returning to its initial
position. Ensure that the sponge is clean before performing a sensor cleaning.
5) Do not perform a sensor cleaning if the ambient temperature is below freezing.
