INSTRUCTION MANUAL
EM201B UEi EM201B Electromic Manometer Electromic Manometer

INTRODUCTION

The EM201B provides a simple, time-saving alternative to U-tube pressure measurements. Use the UEi EM201B to measure gas supply and draft pressures in residential or light commercial properties. The differential mode provides a convenient method to measure pressure drops.

SAFETY RULES

WARNING!
Before every use, check to be sure the meter and its tubing are free from breaks or blockage. While using the meter, if you suspect gas is leaking, or if you can smell gas, close off the gas supply and ventilate the occupied space. Identify and repair the source of the leak before continuing with the test. In the interest of safety, this instrument should only be used by trained, competent professionals who know the hazards and consider the risks of working on and with industrial equipment.
The meter does not measure water pressures; under these conditions they will fail. Do not exceed 10 PSI input pressure

FEATURES

EM201B

Dual input differential measurement to ±60 In-WG
Measures in: In – WG, mBar, PSI and Pa (auto range to hPa)
Ruggedized, including rubber boot with integral magnet
Auto power-off after 60 minutes
Dynamic Min/Max value capture
Data hold
Back-lit display
3 Year limited warranty

OPERATING INSTRUCTIONS

To turn the meter on press the power button for 2 seconds.

Zero the meter Prior to use, the meter must be zeroed. To do this, ensure the meter is in a non-pressurized area, and press and hold the ‘ZERO’ button for approximately four seconds. The display will show ‘888’ to indicate that the zero function has occurred.
Measure Pressure
Connect the flexible tube between the meter and the pressure source.
When performing single input measurement use the positive input. Positive pressures will display as positive results, and negative pressure will display a negative result.
To perform pressure with respect to a different area, connect a tube to the positive port, place the end of this tube to the area to be measured and leave the negative port open. Results will show the pressure in the target area with respect to the area the meter is located Use both the positive and negative ports to perform differential measurements. Place the positive port in the area expected to have a higher pressure, and the negative port in the area of lower expected pressure.
SCALE
To select the desired units press “SCALE”. Repeated presses of this button will scroll through PSI (pounds per square inch), In-Wg (Inches water gauge, or water scale), mBar (millibar), or Pa (Pascals). On the Pascal scale the meter will automatically switch to hectopascals (hPa) when the reading exceeds 1000 pascals. 1000 pascals is equal to 10 hectopascals.
DYNAMIC MIN/MAX
The EM201B will capture values for both the minimum and maximum pressure measured. To reset press MIN/MAX until the display shows “- CLr”. This will reset the values stored for minimum and maximum measured without the need to disconnect and zero the pressure measurement. Captured values can be displayed in any available scale.
HOLD
The EM201B has a display hold feature. Press this during reading to freeze the display. Press again to return to actual measurement.
BACKLIGHT
The EM201B has a backlit display. Press to turn on or off the back light feature. The back light will stay on until the button is pressed again (NOTE: using the back light significantly reduced battery life)
OVER RANGE (OL)
If the input exceeds the meter range “OL” will be displayed. Immediately disconnect from the pressure supply safely to reduce chances of damage to the instrument.
