Changing Measurement Function and Range
As the 4601 includes three AD converters (ADC1 to ADC3), it can measure three points simultaneously.
The three measurement points are shown below, and among which ADC3 has eight measurement
functions.
The ADC3 function is selectable from the eight functions in the DC source mode; however it is fixed to
reference cell current measurement Ir in the sweep source mode.
This section describes how to set the above eight measurement functions and ranges.
(1) ADC1:
Output voltage measurement
Vm
(2) ADC2:
Output current measurement
Im
(3) ADC3:
Reference cell/external voltage/temperature measurement
Ir
: Reference cell current measurement
Em
: External voltage measurement
Tc1 : Ch1 T-type thermocouple measurement
Pt1
: Ch1 resistance bulb (Pt) temperature measurement
Ad1 : Ch1 IC sensor AD590 temperature measurement
Tc2 : Ch2 T-type thermocouple measurement
Pt2
: Ch2 resistance bulb (Pt) temperature measurement
Ad2 : Ch2 IC sensor AD590 temperature measurement
