4.7 Limiter (Compliance)
For a voltage source, the current limiter is set. For a current source, the voltage limiter is set.
Appropriate settings of these limiters can prevent damage due to over-voltage and over-current to the device.
The 6243/44’s limiters for both voltage and current have both + and - polarities, and the set limiter values
(non-polar) are applied for both + and - polarities.
NOTE: When an external power source (V B ), such as a battery is connected, set the voltage source value (V S ) and
voltage limiter value (V
L ) to a value higher than the V B as shown below.
|V
B | <|V S | or |V B |< |V L |
If V S or V L is set to a smaller value than V B , overload or reverse polarity source may be generated.
4.7.1 Limiter Setting Ranges
The limiter setting range is restricted by the source value.
Table 4-10 and Table 4-11 show the limiter setting ranges in relation to the source values.
• The minimum setting value for the limiter is 300 digits of the limiter range. Lower setting than this
is not possible.
