[1] The maximum open voltage is < 2.8 V. For instant continuity, the built-in buzzer sounds when
resistance is <10% of each resistance range.
[2] The accuracy of 1 kΩ and 10 kΩ is specified after Null function, which is used to substrate the test
lead resistance and the thermal effect.
[3] For the range of 100 MΩ, the R.H. is specified for < 60%. The temperature coefficient will be 0.15
times of specified accuracy as > 50 MW..
[4] Overload protection: 1000 V R.M.S. for circuits < 0.3 A short circuit current. The built-in buzzer
sounds when reading is approximately below 50 mV and audible single tone for normal forward
