Error Correction
When errors occur, they should be corrected as shown below.
Display Nature of error
Pressure being applied is
above the rating.
Memory data has probably been
corrupted in some way.
Entire display
Battery voltage is low.
flashes
These products are convenient for measuring line pressure easily without the need to remove piping or stop supply pressure, etc.
Switching between pressurization and atmospheric
release can be easily performed by switching the control.

Maintenance

• Span calibration method
Caution
Do not touch the span calibration trimmer except when performing
span calibration.
1. Perform zero clear at atmospheric pressure.
2. Apply the maximum rated pressure, and calibrate the span while
comparing with a standard pressure gauge.
3. If the display value of the compact manometer is "0" after returning to
atmospheric pressure, then calibration is complete.
If the display value is not "0," calibrate again by repeating steps
1 and 2.

• Replacing the batteries
When battery voltage becomes low the entire LCD will flash.
When the LCD flashes replace the batteries. Use 2 pcs. of type AA dry
batteries.
Caution
To replace the batteries, turn the power OFF and replace them
within approximately 30 seconds.
When not completed within 30 seconds, "Err" will be displayed. In
that case, perform zero clear once again.
In the event that the display runs out of control, remove the batteries for
one minute or longer, and then perform zero clear again after inserting
the batteries and turning on the power.
Pressure can be supplied or stopped by inserting or
removing a tube.
