1.0 To operate
Using the Bluelab Truncheon®Nutrient Meter to measure nutrient conductivity
involves placing 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 Truncheon®Nutrient Meter (Truncheon Meter).
Figure 1. Bluelab Truncheon® Nutrient Meter
Measure conductivity
Place probe into nutrient solution and take
reading as indicated by the flashing lights.
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’.
Note: For very cold or very hot temperatures it will
take 1-2 minutes for the probe to reach solution
temperature. To help decrease time taken to
reach the solution temperature, place the probe
in an area where there is a strong movement of
solution, or stir solution with the probe.
Obtain another reading
To take another reading, simply place back in
solution.
Clean probe
We recommend the probe be cleaned once
every two weeks according to the Cleaning
and Maintenance instructions. This can vary
depending on frequency of use.

2.0 Cleaning and maintenance
Cleaning the Truncheon Meter probe frequently ensures accurate readings.
Clean the probe with a liquid scourer cream used in home bathrooms and
kitchens such as ‘Jif’, ‘Liquid Vim’, ‘Soft Scrub’, ‘Cif’, or ‘Viss’. Never use scented
varieties of cleaner as they affect the probe functions.
Remove shroud
Twist the shroud 90 degrees and then remove the
shroud.
Clean probe face
Place one or two drops of unscented liquid scourer,
such as ‘Jif’, ‘Liquid Vim’, ‘Soft Scrub’, ‘Cif, or ‘Viss’
on the probe face. Rub probe face with your finger or
Bluelab Chamois firmly and vigorously to clean.
Rinse 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.
Replace shroud
3.0 Battery replacement
The Truncheon Meter is powered with 3 x AA type standard or alkaline
batteries. Do not use rechargeable 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.
Remove old batteries
Unfasten battery cap and tip out old batteries.
Check 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.
Fit new batteries
Insert the new batteries positive (+) end down into the body.
Replace battery cap
Refasten battery cap. There must be no space left between
the cap and body to ensure the unit remains 100%
waterproof.

4.0 Troubleshooting guide
Trouble Correction
Truncheon Meter turns off
before reading taken.
Take out of solution for 3-5 seconds.
Dip in solution again and take reading.
Truncheon Meter not lighting
when dipped in solution.
Clean the probe. If this is unsuccessful, replace
batteries. Do not use rechargeable batteries.
Truncheon Meter gives low
readings.
Clean the probe.
Ensure unscented cleaner is used eg. plain ‘Jif’, ‘Soft
Scrub’, ‘Liquid Vim’, ‘Cif’ or ‘Viss’.

Information about the scales available on the
Bluelab Truncheon®Nutrient Meter
CF and EC
CF and EC are measures of electrically charged nutrient ions in a solution.
Pure water will not conduct electricity. Water usually conducts electricity because it
is full of impurities, in our case, electrically charged nutrient ions. The two black dots
on the end of a nutrient probe are called electrodes. When these are placed in a
solution, an electrical current passes from one electrode, through the water to the other
electrode and counts the number of electrically charged ions present. This represents
the units measured - EC or CF.
ppm measures parts per million
There are many different scales used for different industries around the world and
for many different reasons! Did you even know there are more than two scales? The
most widely used scales in Hydroponics are the 500 scale, 650 scale and the 700 scale.
What’s the difference?
The ppm 500 scale is based on measuring the KCl or potassium chloride content of
a solution. The ppm 700 is based on measuring the NaCl or sodium chloride content
of a solution. Individual nutrient ions have different electrical effects! The true ppm of
a solution can only be determined by a chemical analysis. ppm cannot be accurately
measured by a CF or EC meter.
They are present on Bluelab products as a conversion guide only.
The conversion is as follows;
2.4 EC x 500 = 1200 ppm (500 scale) or 1200 ppm / 500 = 2.4 EC
2.4 EC x 700 = 1680 ppm (700 scale) or 1680 ppm / 700 = 2.4 EC
If you are wanting to measure your solution in ppm, you will need to know the
following:
• What ppm scale is your meter using?
• Which calibration standard should you use for your meter?
• What ppm scale is your nutrient referring to?

Bluelab Probe Care Kits
The instrument is only as accurate as the probe is clean!
Probe cleaning is one of the most important parts of owning and operating
any Bluelab meter, monitor or controller. If the probe is contaminated
(dirty) it aects the accuracy of the reading displayed.
The probe surface is where the instrument takes the reading of the solution. The information is sent
back from the probe to the electronic brain of the instrument.
A calculation is then done in the instrument’s brain or micro computer and a reading is displayed. If the
information sent back from the probe is inaccurate due to probe surface contamination then the reading
will be inaccurate. Cleaning the probes is a very easy task and will prolong the life of the probes.
