A series of diagnostic tools is grouped together under the SETUP>MORE>DIAG
menu, as these parameters are dependent on firmware revision (see Appendix A). These
tools can be used in a variety of troubleshooting and diagnostic procedures and are
referred to in many places of the maintenance and troubleshooting sections of this
manual (see Sections 9.1 and 9.2).
This section shall focus on the test channel analog output.
The T700 calibrator comes equipped with one analog output. It can be set by the user to
carry the current signal level of any one of the parameters listed in Table 4-14 and will
output an analog VDC signal that rises and falls in relationship with the value of the
parameter.
Pin-outs for the analog output connector at the rear panel of the instrument are:

Table 4-13 lists the analog I/O functions that are available in the T700 calibrator.
Shows the status of the analog output calibration (YES/NO) and initiates a calibration

Configures the analog output:
1
: Selects the signal type (voltage or current loop) and full-scale value of the
