Operation
The calibration procedure is as follows. The figures below are for a PZiG-1000.
(1) Install the pump and pump to match the actual piping conditions, and set to the trial operation mode
(2) Pour the solution to be actually used into a measuring utensil (e.g. graduated cylinder) capable of measuring the
maximum discharge volume per minute of pump operation.
(3) Insert the suction-side end of the pump piping into the graduated cylinder, and
release air.
* It is more convenient to use the measuring piping if this is provided on the
tank.
(4) Turn the stroke length adjusting dial to set the actual stroke length to be used.
Do not change the stroke length after the maximum discharge volume has been
set.
(5) Press the MODE key several times until the display changes to mL/min.
If the pump is operating, press the STOP key to stop pump operation before per-
forming this operation.
(6) Press the SET key to display the discharge volume setup screen. Press the FUNC key to enter the calibration
mode.

(7) Note down the level of the solution in the graduated cylinder.
(8) Press the START key.
The pump operates for one minute (300 times) and comes to a stop.
(9) Check the level of the solution in the graduated cylinder, and measure the amount of decrease of the solution.
(10) Press the FUNC to return to the discharge volume setup screen.
(11) Press the UP/DOWN key to set to the value calculated in step (9). (when the measurement value is 1010 mL)
(12) Press the SET to return to the discharge volume setup screen.
Remarks
When the screen returns to the discharge volume setup screen, the discharge volume setting value will not change.
However, the stroke spm of the pump has changed.
(13) Set the discharge volume as necessary using the UP/DOWN key.
(14) Turn the pump OFF, and restore the piping.
■Calibration
The specification capability of this pump is the maximum discharge volume at 300 strokes (on the PZiG-1000, 1000
mL/min). However, the discharge volume does not always match the actual discharge volume depending on the operating
conditions, product differences, and stroke length setting.
For this reason, the actual discharge volume per 300 strokes is measured, and the maximum discharge volume is stored to
the pump's memory. This eliminates any error between the preset discharge volume on screen and the actual discharge
volume.
