How to take your first reading
To take your first reading, follow these steps.
1. Remove the Truncheon from the packaging and ensure the shroud is fitted. (The shroud must be present as readings taken without it will be inaccurate.)
2. Submerge the probe head into your solution.
3. Wait 10 seconds or so for the thermistor to come to solution temperature.
Note: For cold or warm temperatures, it may take 1-2 minutes for the probe to reach solution temperature. Try placing the probe in an area where there is strong movement of solution, or stir the solution with the probe.
4. Read the measurement displayed by the blinking LEDs. If the flashing lights are alternating between two numbers, the measurement is the value between those two numbers. For example, if the lights are alternating from 0.8EC and 1.0EC, the reading is 0.9EC.
For the Truncheon Commercial, if the measurement is between two points the lights will blink more frequently closest to the measurement.
Tip: Besides being used to measure nutrient levels, the Truncheon Meter can also be used to mix your nutrients into your solution.
5. The Truncheon will turn itself off after around 10 seconds. If further measurements need to be taken, take the Truncheon out of the solution, wait a few seconds, and place it back in. It will turn on again.
6. We recommend the probe be cleaned and accuracy verified in Bluelab 2.77 EC Solution once every month.
