Introduction
The A D T 6 8 X digital pressure gauge is designed to offer a truly compact,cost effective digital pressure
gauge to cover a wide range of applications. It is not only can calibrate the precision pressure gauge,
industry pressure gauge, blood-pressure meter and other pressure gauges, but also it can measure
the high-accuracy pressure.

Calibration
It is recommended the A D T 6 8 X is re-calibrated once a year by the skillful
professional. Otherwise, the random operation may be effects the inner
parameter and weaken the measure performance. The A D T 6 8 X should be pressurized to full scale
and release all pressure. In order to achieve the best calibration condition, please do the prepressurizing
three times at least.If the calibration process is irregular, please use the cancellation function.
Notice: the cali bration must ac cordi ng to the standar d conditions.
1. Calibration c onditions
(1) Environment:Temperature: 20℃±2℃; Relative humidity: (45-75) %;
Atmosphere pressure: (86~106) kPa.
(2) Standard pressure source.
2. Calibration p rocess
Select Menu to enter the calibration menu. There are 2 different pressure gauges:
(1) Single scale gauge: Two-point pressure calibration, the default is higher/lower limit.
The sequence is higher limit > lower limit.
(2) Dual scale gauge: Three-point pressure calibration, the default is lower/high limit and zero.
The sequence is higher lower limit > zero > higher limit.
The calibration point can be modified if it is meet following conditions:
(1) The first point value is less than 2 point;
nd rd
(2) Or, the 2 point value is less than 3 point.
Example: The A D T 6 8 X with (0~100) kPa
(1)Select calibration menu (as figure1),then input password "218"
and press enter calibration menu(as figure2、figure3、figure4);
Fig ur e1
(2)Select and press to display the calibration value of lower limit, as figure 5. If use needs to modify

this calibration value, please input the desired value. Otherwise, please press to confirm ;

(3)To calibrate lower limit point: Press to confirm till the actual pressure value is
stable. As Figure6;
(4)Display higher limit point: As Figure 7, please input the desired data if user needs to modify the calibration
Value. Otherwise, press to confirm;
(5)To calibrate higher limit point: Press to confirm till the actual pressure value is stable. As Figure 8.
(6)The screen returns to the calibration menu, the 2 option changes to .That shows the calibration is
finished and effective,as figure9.
