Test Sequence - Honeywell IQ Express Reference Manual

between the pump and the MultiPro IQ
Express Dock as shown below. The nubs
on the spacer should face down and be
flush with the IQ Express Dock housing.
Once the spacer is in, insert the detector
into the dock.
Once the dock recognizes the instrument,
it will show the following screens.
Once the connection is made, the IQ
Express will display "Connected", followed
by the instrument type, software version
and recognized sensors.
Note: MultiPro Instrument firmware
version 1.26 or greater is required for
interface with the MultiPro IQ Express
Dock. Attempts to use the MultiPro IQ
Express Dock with instruments with
earlier firmware versions will result in
errors.
If the dock recognizes the MultiPro but is
unable to maintain the connection, the
following screen will be shown:
See section 4.2 for more information of
connection issues

4.1 Test Sequence

Once the instrument has been
recognized, the zero calibration will begin.
Performing the
fresh air calibration in a contaminated
atmosphere will lead to inaccurate and
potentially dangerous readings. The IQ
Express must be located in a fresh air
environment containing 20.9% oxygen
and no toxic gases during calibration.
If fresh air is unavailable, a cylinder of
"zero air" containing 20.9% oxygen
and 0 PPM toxic gases must be
connected to the fresh air port with a
demand flow regulator and a piece of
tubing whenever an instrument is in
the MultiPro IQ Express Dock.
Once the zero calibration is complete, the
dock will flow gas to the instrument in
order to perform the "bump" test. If the
instrument is due for calibration, the dock
will bypass the bump test and proceed
directly to the span calibration.
Once the instrument responds to the gas,
the dock will analyze the response to
determine if the instrument passes the
bump test.
The gas detector will pass the bump test if
the sensor response to the gas is within
10% if the reading is lower than the
expected sensor output or within 20% if
the reading is higher than the expected
sensor output. If the bump test is passed,
the dock will proceed to the alarm tests.
If the instrument fails the bump test or if
the instrument's calibration due date has
passed, the dock will automatically bypass
the bump test and proceed to a full
instrument calibration without further input
from the user.
Following successful bump test or
calibration, the dock will test the
instrument's alarm systems.
If all alarms are operational, the following
screen will be shown.
See section 4.3 for further details on
assessing test failures.
If all tests have been passed, the following
screen will be shown.
