Inspection and Installation

current rated current, use several pieces of red and black test cables. For

example, the maximum current is 1,200A, then 4 pieces of 360A red and

black cables are required.

4. (Optional) Install the load input terminal cover.

5. Directly connect the other end of the red and black cables to the DUT

terminal.

Remote measurement

Remote sensing is used to counteract the effect of lead resistance. For

example, if you connect a power supply to the DC Load, the voltage at the

power supply's terminals will not be the same as the voltage at the DC Load's

terminals if there is a current flowing because of the finite resistance from the

wires. Using remote sensing, you can sense the voltage at the power supply's

terminals, effectively removing the effect of the voltage drop in the connection

wire.

When using remote sensing, the power displayed by the instrument includes

both the power dissipated inside the instrument and the power dissipated in the

leads from the power supply to the DC Load's input terminals.

Sense terminals in the rear panel displayed as follows:

Remote Sensing: SENSE (+) and SENSE (–) are the remote sensing inputs.

By eliminating the effect of the inevitable voltage drop in the DC load leads,

remote sensing provides greater accuracy by allowing the DC load to regulate

directly at the source's output terminals.

Before using the remote measurement function, you must first set the load to

remote measurement mode. The steps are as follows:

1. Press [Shift] + [9] key into the menu.

2. Press Right/Left key to select SENSE, press [Enter] key to confirm.

3. Select ON, then the remote sense function has been set.

Note:

When not using the remote measurement function, press the OFF key to

close the remote measurement mode.

4. Refer the following diagram to connect test cables.
