How to calculate accuracy
Ex.) AC voltage measurement (ACV)
Reading: 100.0 V
Range accuracy: ± (1.6 %rdg + 7 dgt) in the 600 V range
Measuring error: ± (100.0 V X 1.6 % + 7 dgt)= ± 2.3 V
True value: 100.0 V ± 2.3 V (from 97.7 V to 102.3 V)
* 3 dgt in the 600 V range corresponds to 0.3 V.
The product specifications and its appearance described
in this manual are subject to change without prior notice
for improvement or other reasons.

Battery voltage: within the battery effective rage
"test voltage=rated output voltage" means a rated voltage
of the output voltage. The output voltage can go down
depending on the load, if the load resistance is lower than
the lowest resistance described above.
Ex. When measuring 0.1 MΩ with a test voltage 500 V, the
actual output voltage will be 100 V (=1 mA X 0.1 MΩ).
