FORMAT?

FUNC

MEASUREMENT	UNITS STRING
Scaled “MX+B”
Volts DC	“VDC”
Volts AC	“VAC”
Resistance	“OHMS”
Frequency	“Hz”
Temperature	“C”
Temperature	“F”

Query Response Format

Returns the format presently in use:

The default. IEEE-488.2-compatible. No measurement units are allowed.

Responses are RS-232-compatible, allowing a means of recording the units with the measurement value.

Channel Function Definition

Define the measurement function and range for the indicated channel. Attempting to use the FUNC command when measurements are active results in an Execution Error.

Note

Successful execution of the FUNC command clears any alarm limits and scaling values for this channel. Therefore, you must define a channel’s function before setting alarm limits and/or scaling values for that channel. Also, the FUNC command clears all values in the Review array. FUNC <channel>,<OFF>

FUNC <channel>,<VAC VDC FREQ>,<range>

FUNC <channel>,<OHMS>,<range>,<terminals>

FUNC <channel>,<TEMP>,<thermocouple type>

FUNC <channel>,<TEMP>,<PT>,<terminals>

<channel> = (0 .. 20)

If the channel number is invalid, an Execution Error is generated.

<function> = VAC VDC OHMS FREQ TEMP OFF

If the function is OFF, any additional supplied parameters generate a Command Error.

<range> = AUTO (1 .. 6) (Thermocouple/RTD_type)

Ranges for VAC, VDC, OHMS, and FREQ are listed in the following table. Enter AUTO to select autoranging. Use of any other values causes an Execution Error.

RANGE	VOLTAGE	OHMS	FREQUENCY
1	300 mV	300Ω	900 Hz
2	3 V	3kΩ	9 kHz
3	30 V	30 kΩ	90 kHz
4	150/300 V	300 kΩ	900 kHz
5	Error	3 MΩ	1 Mhz
6	Error	10 MΩ	Error
