8 4.4 SIGNAL INPUTS RATIO: The reference input allows an external voltage to be used as the reference source for conversion. In this mode, the meter reads the ratio of the signal voltage to the reference voltage rather than the true value of the input. Signal Voltage Reading in Counts = Reference Vo...

13 8.0 DUAL-SLOPE CONVERSION At the beginning of a conversion, the voltage across C int is zero. The signal is then applied to the integrator and the voltage across C int rises by the formula: T1 E Cint = Esig R int C int At the end of a fixed period of 10000 counts, T1, the counters are reset to 00...
