Introduction
Mercury Instruments ERX is a microprocessor-based, stand-alone, self-powered data recorder
that measures gas pressure(s), gas temperature, case temperature, and applied power supplies.
Sampled measurements, logged Audit Trail data, alarms, and operating parameters are stored in
non-volatile memory and may be retrieved directly with a laptop computer, Palm Pilot, Pocket
PC, or remotely via modem. Pressure and Temperature, alarms, and other sampled parameters
may be displayed on an optional internal or external Alpha-Numeric LCD (Liquid Crystal
Display).
ERX Recorder is capable of sampling and recording up to three pressure transducers and ambient
and gas temperatures. At the time of manufacturing, the ERX may be fabricated as a wall-
mounted, pipe stand, or as a portable unit in an 800 series case, (three pressure default case) ERX
Recorder (single pressure) or a Mini-AT (dual pressure) case.
Calibrating and serial accessing an ERX Recorder is accomplished by using Mercury
Instruments’ MasterLink32 version 3.50 or greater, Palm Suite, or Pocket PC software.
