4.19.6 DC Power Routines for Calibrating UUTs
4.19.6.1 Interconnections
The general connection scheme for ‘UUT calibration of DC Power Functions is as
follows:-
From 9100 To UUT
Hi Hi
Lo Lo
I+ (Also sources Aux Voltage) I+ Terminal or Second Channel +ve
I- (Also sources Aux Voltage) I- Terminal or Second channel -ve.
For UUTs without safety banana sockets, use appropriate adaptors.
Note that the 9105 lead set is NOT suitable. Use of this will cause an error. A suitable
lead set, 9104, is supplied with the Power Option. No electrical connection is possible
between the Voltage and Current channels of the Model 9100. This is not usually a
limitation as power meters are almost universally equipped with isolated volts and current
channels.
The detail of the required connections is dependent on the nature of the UUT and its
associated current transducer if any.
4.19.6.2 Using the 9100 as a Fixed source.
The following procedure assumes that the instrument is in Manual Mode. In the case of
difficulty, re-read sub-section 3.3.1. Familiarity with the methods of editing screen values
is also assumed (see Section 3).
Calibration Setup
1. Connections Connect the 9100 as described, and ensure that both
instruments are powered ON and warmed up.
2. UUT Select DC Power function.
3. 9100 Ensure that the 9100 is in DC Power Function with Output
OFF.
