OPERATIONAL DESCRIPTIONS

Connection of Sample
For the connections to solar cells to be tested and sensors, see Figure 1-1.
5.1.1
Connection with Output Unit
The output terminal unit can be mounted on either the front or rear panel.
The following figure shows the safety socket terminal output unit CC046010 and the terminal block output
unit CC046011.
The output unit employs a four-terminal configuration. Connect the sample to the output unit so that
SENSE and OUTPUT are connected on the sample terminals.
Figure 5-1 Output Unit
When the cable wiring is long (1 m or longer), connect the sample using twisted pair cables to reduce cable
inductance that may cause response delay as shown in Figure 5-2 (A).
In addition, for micro current (1
A or less) measurement, use shielded twisted pair cables as shown in
Figure 5-2 (B).
CAUTION:
1.
When the output units are mounted on both the front and rear panels, operations will not be guaranteed.
2.
The output unit is equipped with surge arrestors for electrostatic protection. Consequently, the dielectric
strength between each output terminal and the protective earth depends on its surge arrester. Repeated dis-
charge causes the surge arresters to deteriorate.
WARNING:
Do not connect an external power supply or other devices to the output unit when the 4601 is in the
Operate status. It may result in electric shock. Otherwise, the life of the relay in the output unit may
be shortened significantly.
