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.

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.
