:ZCORrect:ACQuire

:SYSTem:ZCORrect:ACQuire Acquire zero correct value

Description This command is used to acquire a zero correct value for zero correction. The value can only be

acquired while zero check is enabled. The internal offset will become the correction value.

Zero correction can then be performed with zero check disabled. The description for :ZCOR-

rect[:STATe] provides a command sequence using an acquired zero correction value.

3.22.13 A/D Controls

:TSControl

:SYSTem:TSControl Control external temperature readings

Parameters = 0 or OFF Disable external temperature readings

1 or ON Enable external temperature readings

Query :TSControl? Query state of temperature readings

Description This command is used to control external temperature readings. When enabled (and the Model

6517-TP connected to the instrument), the Model 6517A will make external temperature read-

ings. Note that ETEMperature has to be a selected data element in order to include the temper-

ature reading in the data string. See paragraphs 3.17 (:FORMat:ELEMents) and 3.23

(:TRACe:ELEMents).

:HSControl

:SYSTem:HSControl Control humidity readings

Parameters = 0 or OFF Disable humidity readings

1 or ON Enable humidity readings

Query :HSControl? Query state of humidity readings

Description This command is used to control humidity readings. When enabled (and the Model 6517-RH

connected to the instrument), the Model 6517A will make humidity readings. Note that HUMid-

ity has to be a selected data element in order to include the humidity reading in the data string.

See paragraphs 3.17 (:FORMat:ELEMents) and 3.23 (:TRACe:ELEMents).

:HLControl

:SYSTem:HLControl Control A/D hardware limit

Parameters = 0 or OFF Disable A/D hardware limit

1 or ON Enable A/D hardware limit

Query :HLControl? Query state of A/D hardware limit

Description This command is used to control the A/D hardware limit. With the hardware limit ON, the “Out-

OfLimit” error message is enabled to indicate that an out of range noise spike has occurred.

Disabling the hardware limit disables the error message. With the hardware limit OFF, noise

spikes may cause the reading to be erroneous.
