IMPORTANT: After performing the cleaning procedures rinse the
probe thoroughly with distilled or tap water. Dry it and replace the
sleeve ensuring that the air-vents are nearer to the cable end and
recalibrate the controller.

TROUBLESHOOTING
If the controller does not respond properly or constantly reads zero or
a value close to it, or is in over range, check the probe and cable for
cracks. The cable may be shorted or the probe broken, in which case
they need to be replaced. If the response seems sluggish, follow the
cleaning procedure above.
If there are anomolies such as numbers fluctuating, enure that the
probe has been properly mounted and that it is in a pipe or well
continuously filled with the solution. Air bubbles also disturb the
measurements (especially with HI 3001D) and the probe should be
installed in such a way as to minimize their presence (see Suggested
Installations below).
Note: With industrial applications, it is always recommended to keep
a value close to it, or is in over range, check the probe and cable for
cracks. The cable may be shorted or the probe broken, in which case
they need to be replaced. If the response seems sluggish, follow the

Note: With industrial applications, it is always recommended to keep
a spare probe handy. When anomalies are not resolved with
a simple cleaning or maintenance, change the probe (and
recalibrate the controller) to see if the problem is alleviated.

As with any other liquid contact measurement, ensure that the probe
is installed in such a way that it permanently lies in the solution,
whether in the tank or the discharge pipe.

HI 3001D FOR IN-LINE INSTALLATION
HI 3001D is suitabe for this purpose due to its external 1/2” NPT
thread, 6 Bar (87 psi) pressure rating and the short immersion depth
of 20 mm (0.8”). It can be installed in 1/2” pipes (with the aid of
a “T”). For larger pipe sizes, HI 3001D can be mounted upside down
or vertically.
