4.10. SETUP MORE DIAG: DIAGNOSTICS FUNCTIONS
A series of diagnostic tools is grouped together under the SETUPMOREDIAG
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.
4.10.1. TEST CHAN OUTPUT: USING 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
param
eter.
Pin-outs for the analog output connector at the rear panel of the instrument are:

4.10.1.1. Configuring the Test Channel Analog Output
Table 4-13 lists the analog I/O functions that are available in the T700 calibrator.

SUB MENU FUNCTION
AOUTS
CALIBRATED:
Shows the status of the analog output calibration (YES/NO) and initiates a calibration
of all analog output channels.
MFC_DRIVE_1
MFC_DRIVE_2
MFC_DRIVE_3
(OPTIONAL)
These channels are used by the T700 calibrator internally as drive voltages for
instruments with analog MFCs.
DO NOT alter the settings for these channels.
TEST OUTPUT
Configures the analog output:
RANGE
1
: Selects the signal type (voltage or current loop) and full-scale value of the
output.
OVERRANGE: Turns the ± 5% over-range feature ON/OFF for this output channel.
REC_OFS
1
: Sets a voltage offset (not available when RANGE is set to CURRent loop.
AUTO_CAL
1
: Sets the channel for automatic or manual calibration
CALIBRATED
1
: Performs the same calibration as AOUT CALIBRATED, but on this
one channel only.
AIN CALIBRATED Shows the calibration status (YES/NO) and initiates a calibration of the analog to digital
converter circuit on the motherboard.
1
Changes to RANGE or REC_OFS require recalibration of this output.
