Troubleshooting
Reading Error (Reading
showing 0.00 mg/l in red
numbers along with “Error”
displayed on Sensor Overview)
1.
Check wiring is connected to the correct terminals as detailed on
page 7. Ensure the insulation on the wiring is stripped back far
enough to not interfere with the connection.
2.
Ensure the cable is screwed all the way onto the back of the
probe.
3.
Make sure the sensor input card in Slot #1 is fully seated.
4.
If error continues, contact Factory.
Reading is non-responsive,
unstable, or not maintaining
accuracy.
1.
Ensure sample flow is >250 ml/min.
2.
When a new membrane cap is installed, it may take up to 30
minutes before the chlorine probe starts to register a reading
(>0 mg/l), and a full 2 hours before the reading is mostly
stabilized. It is important the sample has >0.1 mg/l residual
chlorine and ideally exceeding 10% of the probes full scale range
(e.g., >0.2 mg/l for a 2 mg/l range probe).
3.
Verify membrane cap is fully tightened. Dry off the membrane
cap and then ensure the cap is screwed on all the way tight.
4.
Check for air bubbles collecting on the membrane tip (where the
white dot is located). See page 10 of this document for
instructions on how to position probe and adjust flow to deal
with air bubbles.
5.
Ensure the cable is screwed all the way onto the back of the
probe.
6.
Check wiring is connected to the correct terminals as detailed on
page 7. Ensure the insulation on the wiring is stripped back far
enough to not interfere with the connection.
7.
If reading appears unstable or not capable of maintaining
accuracy: Take multiple measurements with DPD test kit to
verify that actual chlorine levels are consistent and stable.
8.
If above steps do not help, remake the probe with fresh
electrolyte and retest.
9.
If above step does not help, remake the probe with a new
membrane cap and retest.
10.
Probe failure. Contact factory for further guidance.
Cannot achieve 1000 ml/min
flow without overflowing the
probe chamber.
1.
Drain line not properly installed and there is too much
backpressure which is preventing a free-flowing drain. The
drain line needs ideally flow straight down to an atmospheric
drain using minimum ½ inch ID tubing. Keep horizontal runs to a
minimum and there must not be any uphill runs or loops in the
drain line. Do not allow the end of the drain tubing to be
submerged under water as this will create backpressure.
