DI–710 Series and DI-715B Series Hardware Manual

The following channel selection grid is typical when a DI-75B is used with a DI-715B. A total of sixteen signal con-
ditioned inputs are available for data acquisition. Channel 17 may be enabled as Digital but must be accessed using a
DI-705 (with CABL-7) through the EXPANSION OUT port.
See the Dataq Instruments Hardware Manager Help files to configure channels for DI-75Bs connected to stand-alone
models.
Calibration
Each 5B module has an Input and Output equivalent printed on it for calibration purposes. Each channel should be
calibrated for its specific 5B module. Calibration for the DI-75B modules is completed exactly the same as for DI-
715B modules. See “Calibration and Gain Settings” on page 32 for more information.
Gain
The signal conditioned (or DI-5B module) channels on the DI-75B output ±5 volts to the host instrument. Since the
DI-715B is a ±10 volt input device, each DI-75B signal conditioned channel in use should be set to at least a gain of
2 so they have a full scale measurement range of at least ±5 volts. Use the same method described at “Gain” on
page 33 to set the gain of the DI-75B signal conditioned inputs.
Installing Shunt Resistors
To use the Current Input Modules (DI-5B32 and DI-5B42) you must install a shunt resistor (provided with purchase
of 5B module) for accurate readings. Instructions for the DI-75B are the same as instructions for the DI-715B. See
“Installing a Shunt Resistor in DI-715B Models” on page 29 for instructions on installation of shunt resistors.
