Analog Display Note Logarithmic representation of the upper resistance scale allows for quick Voltages of greater than 2000 V may not be applied. Input resis- recognition of the magnitude involved. tance for the voltage measuring range is equal to 5 MΩ. In order to achieve the required accuracy for testing of protective mea- sures, the RANGE key allows for switching to the expanded lower limit measuring range of 100 kΩ...
