Last N = previous measurement reading

F average = (1-x)* F4 + x* F5

N(R/h) = [n*F1 + dead time correction {n*F average}/300

The following graph illustrates the ranges over which F2, F3 and F average are used as the DRM-1’s dead time

correction factor:

9. Calibration Summary for the DRM-1D/2D

9.1 Preface

9.1.1 Calibration Factors

The DRM-1D/2D requires only one calibration point which requires only one change to Factor 1 (F1) in the

eter Calibration software. Once the F1 factor has been set performed, linearity verification should be

performed.

The DRM-1D/2D can be calibrated via the RS232 communication port with a NULL modem adapter.

Switch to the ON position dipswitches 1&2 for RS232 and the calibration will be performed by using the Meter

Calibration software. Refer to section 10.1 for instructional use of the calibration software

9.1.2 Calibration Ranges

F1 is recommended to be set at 0.1 to 0.2 mR/h.
