Operating Instructions
Using the Bluelab Commercial Truncheon to measure nutrient conductivity involves
warming the probe sensor head in the solution, followed by measuring and reading
conductivity values on the stem scale indicator light. Figure 1 shows the Bluelab
Commercial Truncheon.

1Warm Sensor Head
Place probe into nutrient solution for 1-2 minutes to reach
the nutrient temperature.
Measure Conductivity
Briefly remove Truncheon from solution then place it back
for 1-2 seconds.

3Read Conductivity Values
Remove Truncheon from the solution and read indicator
light values on stem.
Note: If the lights are dancing between two values, the reading is
between those two values eg. lights dancing between ‘6’ and ‘8’
indicates a reading of ‘7’. You can also count the number of flashes
between two values ie. ‘28’ and ‘32’, two flashes on the ‘28’ light
and then two flashes on the ‘32’ light would indicate ’30’.
4Obtain Another Reading
To take another reading, allow the Truncheon to switch off
and then repeat the above procedure.
5Clean Probe
The probe needs to be cleaned often, once every two
weeks, according to the instructions on the following page.

Cleaning and Maintenance
Cleaning the Truncheon probe periodically ensures accurate readings. Cleaning
includes using ‘Jif’, a trade name for a liquid scourer cream used in home bathrooms
and kitchens. Similar products are called ‘Liquid Vim’ and ‘Soft Scrub’. Scented
varieties are never used as they affect the probe functions. Follow these steps to
clean the probe.

Battery Replacement
Clean Probe Face
Place one or two drops of unscented liquid scourer, such
as ‘Jif’ or ‘Soft Scrub’ on the probe face and rub with your
finger or Bluelab Chamois firmly and vigorously, to clean
the probe face.
3Rinse Probe
Rinse off all traces of cleaner under running water using
the same finger or other side of Bluelab Chamois. Check
that the water forms a film on the probe face with no ‘beads’
of water. If beading is present repeat the cleaning process.
1Remove Old Batteries
Unscrew battery cap and tip out old batteries.
2Check for Corrosion
Batteries that have been inside the unit for a long length
of time may corrode. Check battery contacts and batteries
for any sign of corrosion. Contacts should be cleaned first
if corrosion is found before proceeding to step 3.
3Fit New Batteries
Insert the new batteries positive (+) end down into the
body.
Replace Battery Cap
Screw on battery cap until there is no space left between
the cap and body. This ensures the unit remains 100%
waterproof.
Replace Shroud
The Truncheon is powered with 3 x AA type standard or alkaline batteries. Do not
used rechargable batteries. Do not mix brands of batteries. Do not mix old with new.
Do not put upside down. Follow these steps to replace the batteries.
