INTRODUCTION
The EM151 and EM201 provide a simple, time-
saving alternative to U-tube pressure measurements.
Use the UEi EM151 & EM201 to measure gas supply
and draft pressures in residential or light commercial
properties. The EM201 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.
These meters do not measure water pressures;
under these conditions they will fail. Do not exceed
10 PSI input pressure
