- Page 2 The EM151 and EM201B provide a simple, time-saving alternative to U-tube pressure measurements. Use the UEi EM151 & EM201B to measure gas supply and draft pressures in residential or light commercial properties. The EM201B differential mode provides a convenient method to measure pressure drops.
- Page 3 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.

- Page 5 Connect the flexible tube between the meter and the pressure source. When performing single input measurement use the EM151 single port or the EM201B positive input. The EM201B positive input is to the right when looking at the front of the meter.
- Page 6 Measure Pressure (Cont.) To perform pressure with respect to a different area using the EM201B connect a tube to the positive port, place the end of this tube to the area to be measured and 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.
- Page 7 4. DYNAMIC MIN/MAX (EM201B ONLY) 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. 5.
