simultaneous measurement
1. Do not apply any voltage to the measuring terminals.
2. Be sure to connect the meter in series with the load object.
3. Do not apply any input exceeding the max. rated current.
4. First turn off the circuit to measure, then cut the part. Connect
the test leads of the meter properly in series with the circuit.
