Sensor Housing Connectors
The ‘leak tight’ sensor housing connectors are designed to accept 6
mm OD polyurethane purge gas tubing for its low oxygen outgassing
rates and best weld purging results.
Small lengths of this tubing will be supplied with your PurgEye®
instrument, so that you can join your normal purge exhaust hose
as required.
We recommend that you purchase your desired length of
polyurethane purge tubing from HFT® to eliminate leaks that might
arise from joining multiple purge hoses together.
Connecting the Purge Gas Tubing
The weld purge gas inlets and exhaust
tubes simply push into the two tube
connectors on the sensor housing cover
as shown with the arrows on the picture.
© HFT®
It doesn’t matter which way around the
tubes are connected.
If the aspirator bulb hand pump is not
being used, always ensure that there is
an exhaust tube of at least 150 mm (6”)
in length connected to the other tube
connector (this may need to be longer
if using very low flow rates, in order
to prevent atmospheric oxygen from
migrating into the sensor chamber).
Extra 150 mm (6”) tail pipe is
included for free flow use
Tube connectors
Understanding the MONITOR
BEFORE TURNING ON continued
PAGE 5
The best way to use your Weld Purge Monitor® is to connect the
exhaust tube from your purging system to one of the quick fit
connectors on the front of the monitor. Then allow the exhaust
gas to flow freely over the sensor, out to atmosphere using the 6”
length of tube provided.
If that method is not practical, then use the probe and hand pump
to extract samples from the inside of the pipe or vessel. The probe
should be placed through a weld gap near the top of the purge
space and inserted so that the bottom of the probe only goes a
short way below the weld zone for most accurate results.
The weld joint must be taped and your probe inserted through the
tape and into the weld gap.
Should the purge gas exhaust be insufficient to use the monitor with
a free flow of exhaust gas (as described above) and if the vacuum
bulb and sampling probe are used instead, the aspirator bulb will
be attached to one quick fit connector on the front of the purge
monitor, while the sampling probe and tube is attached to the other
connector. (See diagram on next page).
Press the standby button once and the unit will turn on, initially
it will display four dashes on the monitor. This indicates that the
reading is over range (>40.00%).
Follow the full-scale calibration procedure to start using the monitor.
(See page 8).

TURNING ON the MONITOR
PAGE 7
Installing the Batteries
Remove the battery cover on the rear of the device and install 2 x
AA size standard alkaline batteries, ensuring the polarity is correct.
Use only alkaline type AA batteries. Be careful not to lose the tiny
screw(s).
Turning on the Monitor (for the first time)
After installing the batteries, the monitor will automatically turn
on. There is no need to press the on/off button. The display shows
immediately 88.88 for a second and will then show a reading above
20.94.
Press the calibration button for the monitor to display 20.94, this
may need to be repeated when the monitor is first used.
Note: Follow the full-scale calibration procedure to start using the monitor,
(see special note overleaf).
Turning on the Monitor (thereafter)
Press the standby button on the right (on/off) and the monitor will
turn on. Initially it will display 88.88 on the screen a second. The
display will then show a reading above 20.94.
CALIBRATION
PAGE 8
Full-Scale Calibration
Carefully remove the sensor housing cover (pull slightly and rotate
the black round cover to remove) to expose the sensor element to
atmospheric oxygen. Replace sensor cover after two minutes.
Then press and hold the calibrate button for 5 seconds. After this
time period the monitor will read ~20.94%. Leave the monitor a
few seconds to ensure the reading has stabilised (this may take a
couple of minutes after being switched on).
If the reading varies significantly then hold the calibrate button
again to re-calibrate the monitor.
Note: It is recommended that the calibration procedure be carried out each
time the monitor is used for a new job to ensure that the gas lines are not
retaining residual levels of argon gas and to ensure that the monitor is starting
with a reading of 20.94%.
MAINTENANCE
PAGE 9
Low Sensor and Low Battery Indicators
When the instrument displays a flashing “!” in
the bottom left corner, it is indicating that it
is time to replace the sensor. See spare parts
list on page 14.
When the monitor displays the battery symbol, © HFT®
replace the batteries, see below.
Installing the Batteries
Remove the battery cover on the rear of the
device, being careful not to lose the screws,
and install 2 x AA size standard alkaline
batteries, ensuring the polarity is correct.
Use only alkaline type AA batteries.

Replacing the sensor
PAGE 10
Installing a New Sensor
•
Carefully remove the sensor housing cover.
•
Always ‘gently’ rotate (quarter turn) the sensor housing cover
while fitting or removing.
•
Remove the sensor using the sensor removal tool by hooking
it into the groove on the black part of the sensor, then simply
rest the removal tool against the monitor and lever the sensor
gently upwards.
•
There is no membrane cover to remove on the sensor.
•
After installation of the new sensor, reset the monitor by pressing
the power button and calibration button at the same time then
carry out the zero correction facility.
Note: No force should be applied to the sensor, the sensor housing or the sensor
cover. Do not squeeze the sensor with the sensor removal tool.

WARNING, USE with CAUTION
PAGE 11
Zero Calibration (Correction) Facility
The PurgEye® 100 ‘IP65’ Weld Purge Monitor® is set for use by
our quality control procedures prior to the product shipping to you.
However, occasionally, it may be necessary to use the zero calibration
facility.
Please use the instruction on the next page for the zero calibration
facility with extreme caution.
Once the zero calibration facility has been used, it is vital that the
instrument is placed on the argon gas facility for the alloted time
schedule as shown on page 7.
The procedure in this instruction booklet should ideally only be
used after fitting a new sensor and not done randomly without
good reason.
ZERO CALIBRATION
PAGE 12
When a new sensor is fitted or where greater accuracy is required
at very low readings, you may want to zero the monitor.
This is done by first completing the full-scale calibration procedure
above and then completing the following steps.
1. Switch the monitor on.
2. With older models, (non IP65 versions) we recommend that
you start with a “Reset”. Push the ‘Cal’ and the ‘On/Off’ buttons
simultaneously and hold for 20 seconds, until ‘Reset’ appears
in the display. Step 3 below is then unnecessary, so continue
from step 4.
3. Repeat the “Full Calibration” procedure (See page 8).
4. Connect the sample tube directly to a supply of 99.99% Argon
with a flow of 1 - 2 litres/min (2 - 4 CFH) using the freeflow
method. (See page 6).
5. When the monitor has been reading for about 10 minutes and is
displaying below 1%, press and hold the calibrate button for 5
seconds. The monitor will indicate calibration mode by flashing
‘CAL’ on the screen.
© HFT®
ZERO CALIBRATION
continued
PAGE 13
6. Once the reading falls below 0.5% the monitor will wait for the
reading to stabilise and then take a reference reading, this should take
several minutes, the longer the better. Once this is complete the screen
will stop flashing ‘CAL’ ›and display ~0.00%.
7. Now repeat the full calibration by pushing the ‘cal’ button until ±20.94
appears in the screen.
Your Monitor is now
ready for use.
Again, do not randomly use this facility. It is preferable that this
zero calibration only be carried out when the PurgEye® 100 ‘IP65’
is fitted with a new sensor.
Note: The longer the purge time and the higher the purity of gas, the better
the low level accuracy.
We will gladly carry out the replacement sensor activity for you and
provide you with an up to date calibration certificate. Please ask
your nearest HFT® Distributor for a quotation, or contact us directly

TROUBLESHOOTING and
FAULT FINDING
A Quick Guide in the Event of Problems
If the reading does not fall below 20.9% after a reasonable purge
time, or in the event that your reading does not pass your expected
level of oxygen, please do the following:
•
Check that the correct purge tubes are used for the quick fit
‘leak tight’ connections in case air is leaking into the instrument.
•
Check the purge gas quality at the source by taking your
PurgEye® 100 directly to the source (i.e. gas bottle) to verify
your purge gas quality as well as ensuring that the connections
are ‘leak tight’.
•
Check the cleanliness of the components being welded.
•
Could there be excessive cleaning material or dirt that might
be outgassing?
Note: Excessive oil and grease will outgas and may produce copious quantities
of oxygen until all contamination has been purged.
If you need to reset the monitor, begin by turning it off.
Then press and hold the “Cal” button and the “On” button
simultaneously. Hold both buttons until the word “reset” appears
on the screen.
You will then need to calibrate the monitor at 20.94% and at 0%.
