DIAGnostic:DMM:CYCLes?
Syntax
DIAGnostic:DMM:CYCLes? {1|2|3|4|5|6}
Description
This command reads the cycle count on one of six relays associated with function selection and isolation on the internal DMM. The relays are numbered "1" through "6", which correspond to relays K102 through K107, respectively.

Description |
|
1 |
K102 |
For resistance measurements, this relay enables the ohms current source. |
|
2 |
K103 |
For dc voltage measurements, this relay connects Input High to the low-voltage
dc input for the 10 Vdc range and below. |
|
3 |
K104 |
For dc voltage measurements, this relay connects Input High to the high-voltage
attenuator for the ranges greater than 10 Vdc. |
|
4 |
K105 |
Input High and Input Low isolation to the backplane. |
|
5 |
K106 |
Ohms Sense High and Ohms Sense Low isolation to the backplane. |
|
6 |
K107 |
Current High and Current Low isolation to the backplane. |
Remarks
The internal DMM is an optional assembly for the Agilent 34980A. An error is generated if the internal DMM is disabled (see INSTrument:DMM[:STATe] command) or not installed in the mainframe.
To read the cycle count on the multiplexer and switch modules, use the DIAGnostic:RELay:CYCLes? command.
See the Agilent 34980A Service Guide for information on replacing relays.
Return Format
The query command returns the cycle count on the specified internal DMM relay.
Example
The following command returns the cycle count on backplane relay 2 (relay K103).
