4.Install Operation
The tested pressure signal acts on the pressure sensor,the signal of pressure
sensor change into electrical signal.the current and voltage measurement
signal will be led into via the terminal on the panel,after the A/D conversion
and the sampling-processing by microprocessor,the final result would be
displayed on the LCD screen.

Connection terminals:
Including terminals for current measurement,voltage measurement,
DC24V output, pressure switch value measurement and a public terminal.
Connect terminals as below;
Light up the display screen.
Starting unit is kPa, press this key to switch unit circularly among
mmHg、mmH2O、bar、mbar、psi、kgf/cm2、MPa and Pa.
Press this key to clear current value as zero drift value.then this gauge
would be already in a clearing zero status when you start it up again.
Press this key for zero point and full scale calibration and linear
revision to insure the accuracy.( Do not use the key if there is no
necessary calibration equipments available)
Starting function is measurement for press,current, temperature.
press this key to switch circularly and then choose the measuring
function your demand.
