345mbar Digital Manometer

Description

WRS-1891, 345mbar Digital Manometer

The meter can measure the differential pressure/positive pressure/negative pressure. There are 11 selectable units, as inH2O,psi, bar, mbar, kPa, inHg, mmHg, ozin, ftH20, cmH2O, kgcm. Equipped with a simple hose connection device, it is used for testing Ventilation and air conditioning system, spot check, clean room, or any gas pressure system troubleshooting. Easy operation and clear reading. it is an indispensable testing tool for HVAC technician, maintenance engineers and science researchers.

Operation for Digital Manometer

• 1. ON / OFF button:
  To turn on or off the power press the ON /OFF button to turn on the power of manometer. When turned on, the screen will be displayed for about two seconds and then will display the normal measurement mode.
• 2. Clearance button:
  When turned on, if there is no input differential pressure, instrument will not be cleared by itself. Necessarily need to be manually cleared, press the HOLD button for about 5 seconds, the screen will show it will be cleared later.

• 3. UNITS button:
  Intermittently press the UNITS button there will revolve various units at the bottom of the screen. These units are as follows: bar, mmHg, Ozin2, Kgem2, psi, inH2O, Kpa, ftH20, inHg, cmH20, mbar.
• 4 .DIF button:
  The pressure value when pressing the DIF buttion subtracting the pressure value before pressing.
• 5. HOLD button:
  Pressing the HOLD button will keep the current measured result. Pressing once more will lift the hold function.
• 6. REC button:
  This button is on the side of the instrument, intermittently press this button will
  display the maximum, minimum, average result in process of recording
  measuring. Meanwhile the other function buttons are locked and cannot be
  operated. Long pressing the REC button for about 5 seconds and it will quit recording mode.
• 7. Backlit button:
  Pressing the backlight button and the backlight will turn on. In dark environment can use this function. Press the backlight button again to turn off the backlight.

Error Codes

• An error message will appear on the display if the meter fails an internal diagnostic test.
  1. Err. 1: Pressure value is over the range.
  2. Err. 2: Pressure volue is below the range.

Battery Replacement

• When the battery power falls low, “BAT” will appear on the LCD. Replace The 9Y batery.
