MEASUREMENT UNITS STRING
Scaled “MX+B”
Volts DC “VDC”
Volts AC “VAC”
Resistance “OHMS”
Frequency “Hz”
Temperature “C”
Temperature “F”
FORMAT? 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.
FUNC 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
23 V3kΩ 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
