Notes:
1. Overload protection: 1000 V R.M.S. for circuits < 0.3 A of short circuit current
2. Maximum open voltage: < +3.1 V
3. Instant continuity: Built-in buzzer sounds when resistance is less than 10.0 Ω
4. The accuracy of 400 Ω and 4 kΩ is specified after Relative function, which is used to substrate the test lead resistance and the thermal effect
