Repeatability Test

Our Repeatability Test is more of a meter quality test. It speaks volumes about how well a meter is designed and the quality of its internal components.

Real-World Scenarios

In the real world we find a number of inexpensive meters manufactured overseas that are poorly designed and comprised of lower quality components. They can prevent a meter user from getting the same reading twice. Or, in some cases, the failure to repeat a reading occurs because the electrical current within the pins somehow changes the properties of the wood. Our Repeatability Test helps determine which meters might lack high quality components.

Test Procedures

Reading Repeatability between readings with the same meter

1. Mark an “X” on the sample where readings will be taken, then take the meter and place at the “X” (or in the case of pins, take a reading around the “X”), and record the reading.
2. After removing the meter, replace it on the “X” and take another reading. Record.
3. Repeat step 2 three additional times, for a total of five readings. Record.
4. Repeat steps 1-3 for each meter.

Note: Mark depth of pins for 3” pins.

Reading Repeatability between different meters of the same model

1. Take the first meter, place it on the “X” (or in the case of pins, take a reading near the “X”, but do NOT reuse the same pinholes), and record the reading.
2. Removing the first meter, replace it on the “X” and take another reading. Record.
3. Repeat step 2 three additional times, for a total of five readings. Record.
4. Repeat steps 1-3 for the second meter.
5. Repeat steps 1-4 for each model with multiple meters available.

Note: For the Inter-Meter Repeatability Test, the averages of each meter’s five readings will be compared with each other.

This test only requires one Douglas fir (or similar) board, in the medium MC range.
