9.4
Tester with current limitation
( 3 MA AC/5 MA DC)
For more details of the "
current limitation", see chap. 14.1 " Safety
current limitation".
On Tester with
"
current limitation", the delay time (dead time) is not
active:
Resolutions and Measuring error for voltage,
see chapt. 9.2.1.
Current tripped based on either: Real current, complex current (effective),
Current peak value,
current change speed (delta I)
Short-circuit current:
max. 3 mA AC / 5 mA DC
Current ranges:
100 µA
1)
/ 1 mA / 10 mA AC / DC
Resolution of current indication:
10 μA (10 mA range)
1 μA (1 mA range)
1 μA (100 µA range)
1)
Note - Tester with Krönes HV plug-in connection:
Based on the plug-
in connector (Chapt. 6.4), a basic current is effected up to 15 µA. This
particularly has affects in the 100 MOhm measurement range. Consider
also Chapt. 3.4.1 "Requirements for connecting lines to the test object
".
.
Measuring error test current:
Note for AC-Complex- or AC-Peak value-
measurement: At measurement range 0.1, 1 mA or 2 mA and grounded
item under test, the measuring error of the „test current“ are higher than
indicated in the following. At all other measurings the item under test can
be isolated from earth or grounded.
