Tips: How to set the digital pressure gauge?
There are 4 keys on the digital pressure gauge and they're POWER key, UNIT key, ZERO key and LIGHT key. The specific key operations and calibration settings are as follows:
- POWER key: Long press POWER key 5s for power on/off.
- UNIT key: Short press UNIT key to change unit according to the order of KPa, PSI, kgf/cm2, Bar, MPa. Long press UNIT key 5s to check peak value (MAX), then short press UNIT key to check valley value (MIN).
- ZERO key: Long press ZERO key 5s to finish zero calibration.
- LIGHT key: Short press LIGHT key, light on/off. The time of light on is about 70s.
Digital air/oil/water/hydraulic pressure gauge can display the measured value in real time. It adopts high-definition 4 digit LCD display with backlight, accuracy 0.5%FS, measuring range -100KPa~60MPa/ -1~600bar/ -14~8702psi. Digital pressure gauge can realize: 1) one-touch clear operation, calibrate and set zero at any time; 2) using panel buttons to directly switch between five international standard units (KPa, PSI, kgf/cm2, Bar, MPa); 3) automatically record the peak value of the measured parameters, and the historical peak data can be traced back.
