CPC 100 V1.41
16 - 2
General
• In the following tables, all guaranteed input data are specified for an ambient
temperature of 23°C ± 5°, a power supply of 230V AC, and after a warm-up
time greater than 25min.
• All guaranteed output data are valid for the period of one year after factory
adjustment.
• The error values of each measurement range (listed under "Accuracy" in the
following tables) are specified in
To obtain the exact measurement error, multiply the displayed measured
value with the given reading error (rd), and add the full scale value multiplied
with the given full scale error (fs).
Example:
– CPC 100 is set to the 800A AC range.
– The display shows a measured value of 720A at I Out.
– The guaranteed error is specified as 0.2% (rd) + 0.2% (fs).
– Therefore, the error is 720A x 0.2% (rd) + 800A x 0.2% (fs)
= 1.44A + 1.6A = 3.04A.
• The listed value of the typical maximum output time "typical time t
max
" applies
– at the high-current 800A AC and 400A DC outputs to a load consisting of
2x6m cables
– at the other outputs to the respective typical output power.
% of the reading (rd) + % of full scale (fs)
Note: All guaranteed specifications refer to standard AC or DC
measurements. Other measurements, such as frequency-selective
measurements, or measurements after a numeric integrator (like
used with the CT-Rogowski test card) can have slightly higher
errors.
Note: Never connect the 2kV output to any of the inputs! The 2kV output is
measured internally.
