3.5 Basic Operating Equations

This section lists the basic operating equations used within the 35360A TRACKER Display to produce its
dose and dose rate measurement values for display on the VFD. These equations are expressed in
terms of a set of basic operating quantities which are described in Table 3-3.

3.5.1 Charge

Although charge is not a value which can be displayed directly by the 35360A TRACKER Display, it is an
intermediate result upon which the dose value directly depends.
Q [nC] = (ADC [counts]

3.5.2 Current

Although current is not a value which can be displayed directly by the 35360A TRACKER Display, it is an
intermediate result upon which the dose rate value directly depends.
I [nC/Min] = (ADC [counts]
