" I n t " while mode key press repeated.
Each item setting methode is refer to next pages.
Save
:
If you complete your setting in the each
mode, Press ENTER once to save and exit to
measure mode.
Press ENTER for more than 3 seconds to save and
exist in the setting mode.
Release User setting mode :
Press ENTER once to save and exit to measure
mode.
If you are not operate this instrument for about 1
minute, It's released user setting mode automatically
and return to measuring mode.
Optimize zero to display and current out automatically
by front key pressed.
CAUTION : Release pressure port free before
zero set
Press MODE for more
than 3 seconds till
appear "Int" on LED
display
Press MODE key once
till appear "PoFS" on
LED display.
Press ENTER once to
set zero and exit to
measure mode. "PoFS"
blink for about 5 seconds
to calculate zero.
Press ENTER key for
more than 5 seconds till
appear "SAvE" on LED
display to save and exist
in the setting mode.
Sampling time setting
It can be set 0.1~5.0 seconds by 0.1 sec resolution.
PLT reading pressure 0.1sec interval for a setting
time and calculate average pressure to display and
4-20mA output.
(ex) setting time : 2 sec
PLT reading pressure 20 times for 2 seconds
and calculate average of measured 20 data to
display and 4-20mA current output.
This functions is useful to measure hunted pressure
Press MODE key for
more than 3 seconds till
appear "Int" on LED
display like left.
Release MODE key then
appear current set time
on LED display (default
set time is 0.5 sec)
Set your sampling time
use up/down key
Press ENTER once to
save and exit to measure
mode.
Press ENTER key for
more than 3 seconds till
appear "SAvE" on display
to save and exist in the
sampling time setting
mode
4mA current setting
This function is set pressure level to 4mA current out.
Generally pressure zero is setting to 4mA current out.
By the way, negative pressure is setting in another
case. PLT can be set any pressure level to 4mA
current out between low and high pressure range.
Low and high pressure ranges are setting in factory.
Press MODE key for
more than 3 seconds till
appear "Int" on LED
display.
Press MODE key once
till appear "P4" on LED
display.
Set your pressure level
to 4mA out use up/down
key
Press ENTER once to
save and exit to measure
mode.
Press ENTER key for
more than 3 seconds till
appear "SAvE" on LED
display to save and exist
in the setting mode
