1. For the 5,000 count mode, divide the number of least significant digits (counts) by 10.
2. For film capacitor or better, using Relative mode (REL ∆) to zero residual on 1.000 nF and 10.00 nF ranges.
3. Least significant digit not active above 10 mF.

Specified accuracy ±100 counts up to
5,000 count (full range) reading. For higher
peak readings (to 20,000 counts),
specified accuracy ± 2% of reading.
1. Reading will be 0.00 for signals below 0.5 Hz.
2. Accuracy specification is relative to the user-adjustable temperature offset, and assumes ambient temperature
stable to ± 1 °C.
3. For ambient temperature changes of ± 5 °C, rated accuracy applies after 1 hour.
4. For repetitive peaks; 2.5 ms for single events. Use DC function settings below 20 Hz. 50 mV range not specified.
5. Frequency greater than 5 Hz, except for VDC, 500 mVDC and 3000 mVDC functions; 0.5 Hz to 1 kHz. Signals
centered around trigger levels.
6. Range/input ratios also apply to current functions. 500 counts or 5 % for 10 A ranges.
