5.2.6
Limiter (Compliance)
For voltage source, the current limiter is set. For current source, the voltage limiter is set.
Appropriate settings of these limiters can prevent DUT damage due to over-voltage or over-current.
The 6247G/6247C limiters for both voltage and current have HI and LO limit values and they can be set
individually.
For the voltage limiter, the HI limit and the LO limit values can set not only bipolar, + /- but also homopo-
lar, + / +, or -/-.
NOTE:
When an external power supply (V
B
) such as a battery is connected in the current source function, set
the voltage limiter values (V
HL
, V
LL
) in the following range against V
B
.
V
LL
< V
B
< V
HL
If these values are set outside the above range, the 6247G/6247C detects overload (OVL) and then sets
Standby.
5.2.6.1
Limiter Setting Ranges
The limit values can be set with the following conditions.
60 digits
(HL value - LL value): Voltage limit values
200 digits
(HL value - LL value): Current limit values in 3
A range
NOTE:
1.
Set the current limit values as large as possible within the required range.
The smaller the current limit values are, the longer the settling time is.
2.
Set the voltage limit values as small as possible within the required range.
For cases where the setting current cannot be applied to a DUT, or the output terminals open, the output volt-
age reaches to the voltage limit values.
