1. FEATURES

* Meter can cooperate with 2, 5, 10, 20, 50, 100, 200, 400 Bar

sensor, new calibration procedures are not necessary when
change the new sensor .

* When change the new pressure sensor, just select

pressure type ( 2, 5, 10, 20, 50, 100, 200, 400 bar ) on the
front panel button. The sensor type will memorize into
the circuit permanently.

* 8 kind pressure units ( Bar, Psi, Kg/cm 2 mm/Hg, inch/Hg,　

meter/HF2 , inch/HF2 , Atmosphere ), unit select by push　　
button on the front panel.

* Full line optional pressure sensors are available.
* Auto power off function, saves battery life.
* Cooperate the external pressure sensor that its output

signal is 100 mV for full scale.

* Zero button on the front panel, easy adjust the zero value

of pressure sensor.

* Available push button gain adjustment, usage for

calibration precisely if necessary.

* Separate pressure sensor, easy for remote measurement.
* Microprocessor circuit assures maximum possible accuracy,

provides special functions and features,

* Super large LCD display, easy readout.
* Records maximum & minimum readings with recall.
* Data Hold function, store the desired value on display.
* Built-in low battery indicator.
* RS 232 PC serial interface, can cooperate the personal

computer used as the Data Logger, Pressure Recorder....

& other modern pressure measuring system.
