Warning

Use only Mercury Instruments manufactured battery packs with part numbers as specified
on the certification label or control drawing. Use of third-party battery packs voids
product warranty, voids intrinsic safety certifications and may impair safety.

Modes of Operations

The ERX Recorder is in one of three operating modes. Each mode is well defined and suited to a
particular purpose.
Operating Modes:
• Sample
• Display list
• Serial

Sample Mode

While in the sample mode, the instrument obtains, stores and compares pressure(s),
temperature(s), and power supply voltage readings with alarm limit set points. If reading
exceeds the alarm limit set points, the instrument outputs a single pulse out the alarm
channel, display 'ALARM' or customer configured message on instruments equipped
with an LCD, and if equipped with a modem, jumps into either a modem configured call-
in sub-routine or an instrument call-in sub-routine.

Display List Mode

An LCD is required for display list mode operation. A push button is used to scroll
through the pre-programmed items. Display list mode contains two lists (display list 1 &
display list 2) and live readings (live enabled). Display list 1 can contain up to six items,
display list 2 up to twelve items. Any of the instrument items maybe programmed in
either list. Live-enable is determined by the instrument installed hardware, number of
pressure transducers and whether equipped with a temperature probe. While in display
mode operation, no changes are possible that will affect the configuration of the ERX
Recorder; it will only display the pre-selected items.
