Ratio range | 0 to 1.0 (1.0 input tap) and 0 to 1.1 (1.1 input tap) |
Resolution | 0.1 ppm of input with seven decades 0.2 |
Absolute linearity | (At calibration temperature and without the use of a correct chart) ±1.0 ppm of input at dial settings of 1.1 to 0.1, ±0.1 (10S)1/3 of input at dial settings (S) of 0.1 to 0 |
