(1) Fine tuning: also called trim handle, screw it to get the exact pressure value you wanted
Note: Fine tuning can not be screwed by using the brute force when it has reached its minimum or maximum, otherwise the fine tuning will be damaged.
(2) Handle pump: repeatedly pull out and press down this handle pump to produce a certain pressure, the maximum pressure produced by this handle pump should not exceed 2.5 – 3 Mpa, otherwise the built-in pressure sensor might be short life or damaged, this handle pump’s function is equal to coarse tuning.
(3) Relief valve:
Before using handle pump to produce pressure, you should close relief valve (screw the valve clockwise).
When the pressure exceeds the upper limit of range, you should open the relief valve (screw the valve anticlockwise) till the pressure is in the range then close valve.
If instrument is not used, the relief valve should be at open status.
(4) Pressure output interface: thread M20x1.5, used to connect to pressure gauge or pressure transmitter.
(5) Stud: used to prevent dust particles from entering the pressure producing system when calibrator is not used, also can tighten it on the pressure output interface to check the gas tightness of pressure producing system when producing pressure.
(6) Exhaust pipe: in order to make calibrator work normally, the air in the pressure producing system should be eliminated by liquid. (Exhaust pipe is only for Hydraulic type)
(7) Battery charging socket
(8) 24V DC+: Power supply produced by calibrator
(9) Common grounding
(10) Current input socket: connect to the “I+ “ of pressure transmitter.
(11) Water cup connection interface: for connecting water cup to inject pressure source medium– purified water, if calibrator is not used, the water cup should be disassembled, then use a cap or something else to cover this connection interface to prevent dust from entering the pressure producing system. (Water cup is only for Hydraulic type)
