– Autorange thresholds:
Down range at: <10% of range
Up range at:>120% of range
–
Since CONF:<function> commands reset all measurement parameters on the specified channels to their default
values, be sure to send the CONFigure command before setting any other measurement parameters.
– If the input signal is greater than can be measured on the selected AC voltage range (manual ranging, see
FREQuency:VOLTage:RANGe command), the instrument gives an overload indication: "±OVLD" from the front
panel or "±9.9E+37" from the remote interface.
– The *RST command will clear the scan list and set all measurement parameters to their factory settings. The
Instrument Preset (SYSTem:PRESet command) will not clear the scan list; however, this command will clear read-
ing memory and all stored statistical data.
CONFigure:STRain:{DIRect | FDIRect} [{<gage_ohms> | MIN | MAX | DEF}, [{<gage_factor> | MIN |
MAX | DEF}, [{<range> | MIN | MAX | DEF}, [{<resolution> | MIN | MAX | DEF},]]]] (@<ch_list>)
DIRect measurements only supported on DAQM901A, DAQM902A, and DAQM908A multiplexer modules.
FDIRect measurements only supported on DAQM901A and DAQM902A multiplexer modules.
Configures the channels for direct 2-wire and 4-wire strain gage measurements, but they do not initiate the scan.
This command redefines the scan list.
The CONFigure command does not place the instrument in the "wait-for-trigger" state. Use the INITiate or READ?
command in conjunction with CONFigure to place the instrument in the "wait-for-trigger" state.
Parameter Typical return
<gage_ohms> = Any numeric value between 80 and 1,100 ohms
Default = 120 ohms
<gage_factor> = Any numeric value between 0.5 and 5
Default = 2
<range> = {100 Ω | 1kΩ | 10 kΩ | 100 kΩ | 1 MΩ | 10 MΩ | 100 MΩ | 1 GΩ}
Default = 1 kΩ
<resolution> = 1 PLC (0.000003 x Range)
(none)
Configure 2-wire strain gage measurement on channel 101:
