Instruction Manual
2-17. Resistance ( )
Selection of the resistance function is described in Figure 2-12. There are
four fixed ranges (200 , 2 k , 20 k , 200 k ) plus the autoranging M
range consisting of three ranges: 2 M , 20 M , and 300 M .
In all fixed resistance ranges (200 , to 200 k ), the test voltage is less than
that required to turn on most semiconductor junctions. This feature,
sometimes referred to as “low power” ohms, aids in troubleshooting by
allowing you to measure resistors independent of effects of in-circuit
transistors and diodes. For the fixed ranges the maximum full scale voltage
across the circuit being measured is less than 250 mV. The autoranging M
ranges have enough voltage to turn on semiconductor junctions (maximum
2.5V full scale), but the current is very low (2.2 A maximum).
