Teledyne 465M instruction manual Diag Menu, Point 5V Output MA Output

7.2.3.DIAG Menu

The DIAG menu (See Figure 7-2and Figure 7-3)contains functions that are useful for testing and configuring external equipment that may be connected to the rear panel I/O of the instrument.

7.2.3.1. Analog Step-Test

When placed in this mode, the instrument will automatically step the analog output through 5 points from 0 to 100 % and display the current value on the front panel. The operator can suspend the automatic cycling and manually control the stepping by pressing either one of the UP / DOWN arrow buttons. To resume automatic cycling, exit the function by pressing CFG and re-enter by pressing ENT.

The 5 points will correspond to the following analog output values depending on whether the output is configured for 0-5V or 4-20mA:

Table 7-3: Analog Step Test Values

Point	0-5V Output	4-20 mA Output
0%	0.00 V ± 0.02	4 mA ± 0.02
25%	1.25 V ± 0.02	8 mA ± 0.02
50%	2.50 V ± 0.02	12 mA ± 0.02
75%	3.75 V ± 0.02	16 mA ± 0.02
100%	5.00 V ± 0.02	20 mA ± 0.02

Press CFG to exit from the Analog Step-Test function.

7.2.3.2. Signal I/O

The Signal I/O menu allows the operator to manually control the various relay outputs and control inputs available on the rear panel of the M465M. This function is useful for testing or debugging external control systems (i.e. dataloggers or PLC’s) to which the instrument may be connected.

See Section 4.5 for additional details on making connections to these I/O signals on the rear panel.

See Table 7-4for additional details on entering the Signal I/O menu.
