Audible threshold: Less than 20 to 150 
Test current: < 1,2mA
3.6. Diode
Diode: Testing voltage approx. 2,8 V, current 1,5 mA, indicate
forward diode approx. value.
3.7. Temperature
Range
0...1000°C
4. Operating instruction
Attention! For reasons of safety the maximal permissible input
voltage towards earth (ground) it isn't allowed to be crossing over
300 V. At disregard there is a risk of injury (electrical shock) and the
risk of damaging of the internal circuits.
Before measuring, check the instrument and the test leads for
possible damaging.
