1VDC, 4VDC, and 16VDC. To select a range, simply specify the range value
(for example, 4 selects the 4VDC range). If you specify a value larger than
one of the first four ranges, the HP E1415 selects the next higher range (for
example, 4.1 selects the 16VDC range). Specifying a value larger than 16
causes an error. Specifying 0 selects the lowest range (.0625VDC).
Specifying AUTO selects auto range. The default range (no range parameter
specified) is auto range.
•
If you are using amplifier SCPs, you should set them first and keep their
settings in mind when specifying a range setting. For instance, if your expected
signal voltage is to be approximately .1VDC and the amplifier SCP for that
channel has a gain of 8, you must set <range> no lower than 1VDC or an input
out-of-range condition will exist.
•
Resistance measurements require the use of Current Source Signal
Conditioning Plug-Ons.
•
The excite_current parameter (excitation current) does not control the current
applied to the channel to be measured. The excite_current parameter only
passes the setting of the SCP supplying current to channel to be measured. The
current must have already been set using the OUTPUT:CURRENT:AMPL
command. The choices for excite_current are 30E-6 (or MIN) and 488E-6 (or
MAX). excite_current may be specified in milliamps (ma) and microamps
(ua).
•
The *CAL? command calibrates resistance channels based on Current Source
SCP and Sense Amplifier SCP setup at the time of execution. If SCP settings
are changed, those channels are no longer calibrated. *CAL? must be executed
again.
