KHA1000
Current range of this product. Select one according to the input current of the EUT.
Set the maximum value as a guide in the operating cycle of the EUT. The peak
current that can be measured is four times the value in the 0.5 A to 10 A range and
2.5 times the value in the 20 A range.
•
The maximum value of input current is 50 Apeak. Exceeding this value
may burn the current detector.
•
If the current detector overheats, the OHP icon appears on the upper part
of the screen. Immediately shut down the power to the EUT to cut the input
current of this product. Restart the test after the OHP icon disappears.
The peak current of the EUT is believed to be reached at maximum power. Keep in
mind the entire operation cycle of the EUT.
6.1.2 Nominal Voltage and Frequency, Pst / d Measurement
Time or Count, Over-range Abort
Menu
Nominal test voltage (typical value). Select one according to the rating of the EUT.
Nominal test frequency (typical value). Select one according to the rating of the
EUT.
For a flicker test, set the Pst (short-time flicker value) measurement time or d
measurement time in seconds.
• Pst Measurement time (s):Selecting Pst Auto F1 of menu page 1/3 lets you enter
a value. The setting range is 30 to 900 (seconds). The
standard specifies “measurement time = 10 minutes.”
Normally, therefore, set it to 600 seconds.
• d Measurement time (s): Selecting Manual at F1 of menu page 1/3 lets you
enter a value. The setting range is 30 to 180 (seconds).
In the case of Manual, the standard specifies
F5 Current Range 0.5 A 1 A 2 A 5 A 10 A 20 A
