Turning on the Backlight
It normally lights up
while the button is be-
ing pressed. In the lock
mode, it lights up when
pressed and turns off
when pressed again.
However, the maxi-
mum lighting time is
approximately one min-
ute.
Zero Clear
The zero point dis-
played at atmospheric
pressure can be auto-
matically adjusted. By
this means it is possi-
ble to eliminate a dis-
play discrepancy at at-
mospheric pressure.
• Turn the power OFF.
• Release the supply
pressure to the at-
mosphere.
• When continuously
pressed for 6 sec-
onds or more, zero
clear is performed
and “CAL” is dis-
played on the LCD.
Lock Mode (Auto power OFF cancel)
The auto power OFF
function is canceled by
activating the lock
mode (auto power OFF
cancel).
When continuously
pressed for 6 seconds
or more, “L” is dis-
played on the LCD.
Moreover, when the
power is turned OFF,
the lock mode is re-
leased.
Auto Power OFF Function
When the power is
turned ON and there is
no button operation for
more tham 5 minutes,
the power will turn
OFF.
Note) For cancelling
this function, refer to
the functions and oper-
ation of the lock mode
(below).

Peak/Bottom Display
Do this when pressure
is being displayed.
Peak display
Displays the maximum
pressure value and “P”
appears on the LCD.
The display will change
if pressure increases
beyond the pressure
value that is being held.
Bottom display
Displays the minimum
pressure value and “b”
appears on the LCD.
The display will change
if pressure falls below
the pressure value that
is being held.
(These modes are
convenient for con-
firming pressure fluc-
tuations.)

Operation and Functions
Note) This operation cannot be done for
the type which does not have the
unit switching function.
Note) Since this is combined with power
OFF operation, the button should
be released at the point when “P”
or “b” is displayed.
1. Press and hold the
POWER and LIGHT
buttons for 3 sec-
onds or more.
Press and hold the
POWER and LIGHT but-
tons for 6 seconds or
more.
