Primary Battery
The Honeywell EC-P2 is a portable, battery operated instrument for the measurement
of gas concentrations in ambient air.
The Honeywell 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 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 Honeywell 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 “D” size alkaline
battery housed in the handle. It will run the unit approximately 75 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 Honeywell 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.

2.1 Operating the Sensor
The Honeywell 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.

Honeywell EC-P2 Instruction and Installation Manual
The normal operating screen displays the information as shown in Figure 2.
The Honeywell EC-P2 is designed to avoid accidental shut-off of the power. To turn
the unit off, the PWR button must be held down for approximately three seconds.
Release the button after the “Power Down” message appears.
2.2 Changing the Target Gas using SMART-CELL Technology
The Honeywell 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 Honeywell
EC-P2 from one gas to another. This procedure can be performed with the unit
powered on or off (see Figure 3).
Unscrew the two stainless steel thumbscrews and remove the black inlet 1.
/ outlet manifold lid from the back of the unit.
To remove the existing SMART-CELL, grip the sides of the cell and pull 2.
it straight out.
Install the desired SMART-CELL by gently inserting it into the socket. Notice 3.
that the SMART-CELL is keyed so it cannot be inserted incorrectly.
Replace the manifold and hand tighten the thumbscrews.4.
Verify proper flow through the sampling wand using the flowmeter 5.
provided.
Note:
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 “D” size battery which should
be replaced every 6 months.
For a variety of target gases, see page 19 for a list of available SMART-CELLs.
Contact Honeywell Analytics if the desired target gas is not listed, as new cells
may be available.
