11. PRECISION*
The electrical parameters of the meter are factory calibrated to 1% of reading.
However, due to variations in product measurement characteristics, the repeatability
(r) and reproducibility (R) are as follows:
PS/M r R
1 1 1
15 6 8
20 7 9
30 9 11
50 13 16
70 15 19
100 19 24
200 29 36
300 37 46
500 51 62
700 62 76
1000 77 94
1500 98 120
PS/M – picosiemens per meter
r = Repeatability - Maximum allowable difference between 2-successive
measurements performed by the same operator using the same meter to test the same
sample.
R = Reproducibility – Maximum allowable difference between 2-measurements
performed on the same sample by 2different operators using 2-different meters.
*Precision is based on a Inter-laboratory Test (ILT) Program conducted in November
2004 under the auspices of the American Society of Test and Materials (ASTM)
International. Since the Program was conducted at room temperature (23ºC – 73.4ºF)
the precision may vary at other temperatures.
