After matching the pressure loss display to the readout value on the standard pressure gauge by
pressing the [UP] and [DOWN] keys, press the [ENTER] key. Calibration input is accepted, and
the screen returns to the Calibration menu.
After calibration is finished, be sure to re-connect the tube to the filter.
* After setting the numerical value, if the [MENU/ESCAPE] key is pressed
before the [ENTER] key is pressed, the screen will return to the
Calibration menu without the newly entered value being accepted.
* The initially displayed pressure loss is displayed with the adjustment
value of the previous calibration reset. For this reason, the pressure loss
may differ from the pressure loss value displayed outside of the
Calibration menu. Perform error measurement for the filter pressure loss
in a different menu after calibration.
Ambient Temp (Ambient Temperature Sensor Calibration)
Prepare a "standard thermometer." The
ambient temperature sensor is located on the
rear panel (TEMP. SENSOR) of the pump unit.
Bring the standard thermometer close to the
ambient temperature sensor.
When "4 Ambient Temp." is selected and the
[ENTER] key is pressed, the current ambient
temperature is displayed with the adjustment
value of the previous calibration reset.
After matching the ambient temperature display to the readout value on the standard
thermometer by pressing the [UP] and [DOWN] keys, press the [ENTER] key. Calibration input is
accepted, and the screen returns to the Calibration menu.
* After setting the numerical value, if the [MENU/ESCAPE] key is pressed
before the [ENTER] key is pressed, the screen will return to the
Calibration menu without the newly entered value being accepted.
* The initially displayed ambient temperature is displayed with the
adjustment value of the previous calibration reset. For this reason, the
ambient temperature may differ from the ambient temperature value
displayed outside of the Calibration menu. Perform error measurement
for the ambient temperature in a different menu after calibration.
* Calibrate the ambient temperature sensor before measuring the suction
flow rate error. If the ambient temperature sensor is calibrated after the
suction flow rate error is measured, the instantaneous and total flow
rate measurement values will be affected by the ambient temperature
measurement error.
