Remote Voltage Sensing
As the DP1116A can provides 10 A output current and 160W output power, the voltage
drop in the load leads must not be disregarded. In order to ensure the accuracy of the
voltage drop while outputting a high current, the DP1116A was designed with a Sense
(remote sense) function. In Sense mode, the system automatically compensates the
voltage drop in the load leads so as to ensure the specified output value can be
consistent with the value received by the load. See the connections below.
Figure 2-12 Sense connection
Operation Steps:
1. Connect the output terminals and the Sense terminals at the front panel of the
instrument to both ends of the load as shown in Figure 2-12. Please pay attention
to the polarity while connecting.
2. Press Sense, the backlight of which goes on and the icon “Sense” is lighten.
NOTE
When outputting a high current, the load leads should be as short as possible,
and it would be best if the two leads can twist together in order to obtain a
better output characteristic.
Please use a twisted-pair as the Sense lead as possible as you can and the
leads should not be twisted with the load leads.
