DI-730 Host Instruments
Typical channel selection grid showing a DI-78B with a host DI-730
All channels (on both the DI-730 and the DI-78B) are enabled on the top row of the Channel Selection grid. The
shaded areas show the channels that are still available on the host DI-730 instrument when the DI-78B is added.
Channels 17 through 32 (channels 1 through 16 on the DI-78B) are defined by DI-8B modules and are enabled by
clicking once with the left mouse button. The isolated differential inputs on the front panel of the DI-730 are still
available.
Configuring DI-78B Channel Gain (you MUST configure gain for proper readings)
The signal conditioned (or DI-8B module) channels on the DI-78B output ±5 volts to the host instrument. Since the
DI-78B connections to the DI-720 Series and DI-730 Series (available through the EXPANSION connector) host
instruments are ±10 volt input devices, each DI-78B signal conditioned channel in use
MUST
be set to a gain of 2, so
they have a full scale measurement range of ±5 volts.
