Introduction

This manual has been prepared to help in the use of the Manning Systems EC-P2 portable gas
detector.

This manual must be carefully followed by all individuals who have or will have the
responsibility for using or servicing the sensor.

Warranties made by Manning Systems, Inc.
with respect to this equipment will be voided if the equipment is not used and serviced in
accordance with the instructions in this manual. If in doubt about a procedure, please contact
Manning Systems, Inc. before proceeding.

1 System Description

The EC-P2 is a portable, battery operated instrument for
the measurement of gas concentrations in ambient air.

The EC-P2 can be converted from one target gas to
another by simply plugging in a different SMART-CELL
for the desired target gas (takes about 30 seconds). This
allows one instrument to detect a number of different
gases.
All calibration and alarm setpoint data is stored on the
individual SMART-CELL so reconfiguration is not
necessary when changing target gases. Extra SMART­CELLs should be kept on the optional sensor keeper
when not in use to keep them “warmed up” and ready
for immediate use.

The EC-P2 utilizes two different batteries to insure that
you’ll never be without power when you need it. The
primary power source is a “C” size alkaline battery
housed in the handle. It will run the unit approximately
48 hours. When this battery is removed or dead, the unit
will switch to its standby power source, an internal
rechargeable NiCad battery, which will run the unit
approximately six hours. When not in use, the unit
should be plugged into the charger to keep this standby
battery charged. If desired, the unit can be run
continuously when plugged into the charger.

The EC-P2 also has advanced capabilities such as data
logging to an Excel spreadsheet, 0 to 1.0 Volt DC analog
output capability, and a sampling mode for taking a
single reading in a controlled, repeatable manner.

A Operating the Sensor

The EC-P2 is shipped ready for use. To power up the
instrument, push the PWR button. The power up
sequence displays first the self check, the sensor full
scale value, the downscale caution level, warning
concentration setpoint, alarm concentration setpoint,
output ranges, software version, then the normal
operating screen.

The unit will then display the instantaneous gas
concentration and is ready for use.

The normal operating screen displays the information as
shown in Figure 2.

The EC-P2 is designed to avoid accidental shut-off of the

4) Replace the manifold and hand tighten the thumbscrews.

5) Verify proper flow through the sampling wand using the

flowmeter provided.

Extra SMART-CELLS should be kept on the optional
sensor keeper when not in use to keep them “warmed
up” and ready for immediate use. The sensor keeper is
powered by an Alkaline “C” size battery which should be
replaced every 6 months.

For a variety of target gases, see page 13 for a list of
available SMART-CELLs. Contact Manning Systems if
the desired target gas is not listed, as new cells may be
available.

The EC-P2 can easily be changed to sense another target
gas by installing the SMART-CELL for the desired target
gas. Each SMART-CELL contains all the calibration and
alarm setpoint information on its internal memory chip,
so recalibration or reprogramming is not necessary
when changing the EC-P2 from one gas to another. This
procedure can be performed with the unit powered on
or off (see Figure 3).
