Fluke 80i-500s, Инструкция, Страница: 7 / 11

PERFORMANCE VERIFICATION
Verify probe accuracy with the test setups shown in Figure 4.
Required test equipment is defined in Table 1. Toriod coil
construction is illustrated in Figure 5. First setup Connection A,
and makes the checks called for in Table 2. (Connect the output
of the probe directly to the signal-in on the phase meter for the
phase check.)
Then disconnect A at the 5100B, and set up Connection B. Make
the first four checks called for in Table 3. (Connect the probe
directly to the phase meter for the phase check.)
CAUTION
Remove the shunt before making the last check at
500A. Otherwise, the maximum current rating of the
shunt will be exceeded.
