Note (1) Above 1000V (RMS), a repetitive beep indicates that the voltage
being measured is greater than the safety voltage for which the
device is guaranteed. The display indicates "OL".
Note (2) Any value between zero and the min. threshold of the measurement
range (0.15V) is forced to "----" on the display.
Specific Specifications in MAX/MIN mode (from 10Hz to 1kHz, and from
0.30V in AC):

Accuracy: add 1% R to the values of the table above.

Capture of the extreme: approximately 100ms.

Note (1) - The display indicates "OL" above 1000A.
Note (2) Any value between zero and the min. threshold of the measurement
range (0.15A) is forced to show "----" on the display.
Residual current at zero <150mA.
Specific Specifications in MAX/MIN mode (from 10Hz to 1kHz, and from
0.30A in AC):

Accuracy (with zero corrected): add 1% R to the values of the table
above.

Capture of the extreme: approximately 100ms.
