Notes:
1 The accuracy for the 2 Ω to 200 Ω range is specified after the Null function is used to subtract the resistance of test leads
and the contact resistance.
2 For the 20 MΩ and 200 MΩ range, the RH is specified for <60%.
3 Resistance measurement is specified to Q <10 and D >0.1; otherwise accuracy is specified as .
4 ESR (Equivalent Series Resistance) measurement is specified according to the impedance measurement and range. The
maximum display is up to 199.99 kΩ and the accuracy is specified as .
