Description

Overview

GAOTek Digital Manometer (Low Range Indicator) is designed to measure the pressure of water column from ± 55 (2 psi) with low range indicator to monitor the pressure. It has 11 selectable measuring units as H2O, psi, bar, mbar, kPa, inHg, mmHg, ozin, fitH2O and kgcm. This manometer is equipped with a simple hose connection easy to operate and accurate in measurements. The maximum pressure is up to 10 PSI with built-in low range and high range error indicator. It is an indispensable testing tool for HVAC technician, maintenance engineers and science researchers.

Operation:

Power Button:

Press the ON/OFF button to turn power on or off. The meter will perform a short self-test when turned on. The meter defaults to the setting used during the last operation.

Zero Adjust and Offset

Before use and without fittings attached to the meter, press the Hold button for more than 2 seconds to Zero the meter. The meter will raise and display “000” from right to left.  0.000 will be display.

If it is desired to offset the meter and display, press the DIF button while asking a measurement subsequent reading will be the difference between the current measurement and the measurement that was on the display when the DIF button was pressed.

Unit 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, Kgcm2, psi, inH20, inHg, cmH2O, and mbar

DIF button: The pressure value when pressing the DIF button subtracting the pressure value before pressing.

Hold:

Press the HOLD button momentarily to freeze the displayed reading the HOLD icon will appear on the upper left hand side of the display. Press the HOLD button gain to return to normal operation.

Record:

The MAX/MIN mode allows the user to view only the highest (MAX), lowest (MIN) or average (AVG) readings with relative time stamp.

  1. Press the Rec button once and Rec appears on the display. The relative time clock also appears in the secondary display and start counting.
  2. Press the Rec button again and Max appears on the display. The Display is now showing the maximum pressure and relative time, it was recorded.
