Table 1-2. General Information.
Measurement Times (typical):
For a 1000 count measurement on a low
loss component on a fixed range:
1kHz, 10kHz
120(100)Hz
When autorange is selected the following
times per range step must be added to
the above times:
1kHz, 10kHz
120(100)Hz
45ms/180ms
150ms/670ms
When U-CL is displayed, the faster
ranging time is selected.
Reading Rate:
Internal - Approx. 30ms between end of
measurement and start of next cycle.
External - Measurement cycle is initiated
by external trigger input.
High D Factor Accuracies:
Typical
(
2,
on 10.00 range).
