SWITCHING THE UNIT ON
Press switch On key , at the start Unit Model number & serial number will be
displayed , then pressure range will be displayed
INSTRUCTIONS
Users/customers are expected not to use the instrument below & above the
pressure range mentioned, this will permanently damage the sensor
Always Connect pressure tubes with leak free joints
Instrument will perform “Autozero” automatically for first time at the start &
a message will be displayed
“Autozero successfully done”
Users can also press zero key manually for 1 second to perform autozero
manually
User can change & select multiple units by pressing unit selection keys
Upper arrow key /Increment key is used to reset the Minimum & Maximum
values of pressure
Display Back light key is used to switch Off/ On back light , it is
recommended to use backlight when only needed to save battery life ,
backlight automatically goes “switch off” after sometime as programmed in
the setting menu

PROGRAM MODE /SETTING MENU
Switch On the instrument & let it perform auto zero automatically & wait till main display starts
To enter into setting menu long press (Zero Key + Light key) together for 3 seconds continuously
The Display shows the following prompt
FOLLOWING MENU OPTIONS ARE DISPLAYED AFTER ENTERING INTO
SETTING/PROGRAM MODE
Enter password 1204 with help of shift (left) key & Up arrow /Increment key, press Zero
/enter Key to enter the password
If no key is pressed for long time, the instrument will come out of program/ setting mode

Step Calibration Mode is full calibration Mode at 10 multiple points( at every 10 % ) covering
complete instrument range to provide high accuracy of 0.1 % FS throughout the operating range
Use this Mode only when you have calibrated external pressure reference source & hi accuracy
pressure display to calibrate this instrument
Connect the External reference pressure source with calibrated display to the instrument &
following procedure.
Enter the 1. Step calibration mode with help of enter key, After the LCD Display shows the
following prompt
