7.5 Zero Point Adjustment

Adjust the zero point of GSP-501FT built-in flowmeter.

①

(If it is not in the calibration mode), activate the

calibration mode and make sure that "25°C tStd"

is displayed. (When the conversion temperature is

set to 20°C, "20°C tStd" is displayed.)

②

Press "MODE Button" twice and confirm that

"0AdJ" is displayed.

Press twice

↓

③

Press "START/STOP Button".

Press

④

The display of blinking "0AdJ"

→

Zero point of

flow rate prior to calibration

→

blinking "0AdJ"

→

blinking "0mL/min" (Zero point of flow rate

after calibration) indicates the completion of zero-

point adjustment. If the zero point is 0mL/min

after calibration, it is normal. If it does not reach 0

mL/min, recalibration is necessary.
