ERROR DISPLAY
If the display is as shown in the right figure, excess current
is flowing due to a load short-circuit. In this case, switch off
the power supply and check the load and output.
Note: The right figure shows the vacuum pressure type sensor. In case of the
positive pressure type sensor, the position of the indicators (red) is symmet-
rically opposite.

FUNCTIONAL DESCRIPTION
Set pressure pointer
Main scale
Power indicator (Red)
Operation indicator (Red)
Note: In case of the vacuum pressure type, the position of the indicators (red) is symmetrically opposite.
Designation
Set pressure pointer
Rotating the set pressure adjuster turns the pointer simultaneously.
(Note)
The value indicated by the pointer represents the set pressure level.
Sets the threshold level.
Vacuum pressure type
Rotating it counterclockwise, sets a higher vacuum level.
Set pressure adjuster
Positive pressure type
Rotating it clockwise, sets a higher positive pressure level.
'Pa' unit scale. It completely coincide with the LED bar display.
Main scale
PE-20 , PE-21 : kPa
PE-22 : MPa
It is an additional scale. It does not completely coincide with the
LED bar display. Use it as a reference.
Pressure unit is,
Sub scale
PE-20: cmHg, PE-21, PE-22: kgf/cm
PE- N: psi, PE- E: bar
Power indicator (Red)
Lights up when the power is ON.
Operation indicator (Red) Lights up when the output is ON.
Pressure indicator (Red) Shows the measured pressure level.
By using the
dicator, the resolution can be increased to twice than that in case
of using the pressure indicator only.

Note: It is possible that the position of the set pressure pointer and the position of the pressure indi-
cator lighting up may not match. Use the set pressure pointer as a reference.
