1. Overview
The IQ Express is an automatic calibration
station for use with the ToxiPro, OxyPro,
ToxiLtd and OxyLtd Gas Detectors. The IQ
Express automatically performs up to eight
critical tests including sensor identification,
instrument performance, bump and alarm
tests and necessary record-keeping
procedures. The station retains a historical
record of instrument testing in the system's
onboard memory.
The IQ Express Dock is available in two
versions. The standard version is able to
process instruments containing O
2
, CO and
H
2
S sensors. The enhanced version adds
the ability to process ToxiPro instruments
for SO
2
, Cl
2
, NO
2
, NH
3
, HCN and PH
3
.
Either type of dock may be operated as a
stand-alone calibration station, or may be
connected to a PC via USB or Ethernet for
increased control over system operations.
When the IQ Express is operated without a
PC interface, it will operate with the last set
of calibration gas settings that were
uploaded into the instrument and will
automatically store data until its memory is
full.
Unless specified at the time of purchase, all
IQ Express Docks are shipped from Sperian
Instrumentation configured for CO/H
2
S
instruments with standard calibration gas
settings. In the event that the dock is to be
used as a stand-alone calibration station for
an instrument with a gas other than CO or
H
2
S, or requires a non-standard calibration
gas setting, the dock must be
reprogrammed with the IQ Express PC
Software.
The IQ Express PC Software must be
loaded onto the PC prior to completing the
physical connection to the PC. When
connected to the PC, the IQ Express will
automatically upload all instrument data into
the PC whenever the instrument is placed in
the dock.
Note: Do not connect the IQ Express to
the PC until the software has been
installed and the PC has been restarted.
1.1 Tests and record keeping
The IQ Express Station automatically
performs the following eight procedures
whenever an instrument is placed in the
dock.
•
Instrument
identification
•
Battery
test
•
Audible alarm test
•
Visual alarm test
•
Vibrating alarm test (if applicable)
•
Fresh air calibration
•
Bump
test
•
Record-keeping
•
Datalogger and Eventlogger download
(IQ Express must be connected to PC to
extract the information from the dock)
In the event that an instrument fails the
bump test, or if the instrument’s calibration
due date has passed, the IQ Express will
automatically proceed to a full calibration
without further intervention from the user.
If the instrument fails any of the tests listed
above, the IQ Express will notify the user
through the display on the dock, and
through the PC if the dock is connected to
the PC and the software is running.
Results of tests and calibration attempts are
stored in the dock and uploaded to the PC if
the software has been loaded and the USB
or Ethernet connection is active.
IQ Express software versions greater than
3.0 will have the ability to download the
contents of the instrument’s datalogger and
eventlogger into a file on the PC that may
be opened with BioTrak software. The IQ
Express must be connected to the PC for
the download to occur.
IQ Express software versions greater than
6.20 have the ability to update the ToxiPro’s
firmware/flash file.
