Used to check resistance of electrical bonding and ground posts (see SWPM 20-20-00). Auto range/test, RS-232 data port, range: 0.01 – 19,999.0 milliohms (0 – 20 ohms), memory, 4 1/2 digit display, accuracy: 0.1% of readings, +/- 1 display count. Note: The M1B Milliohm Meter is identical in all appearances/operation/performance/specifications to the original M1; except M1B has an extended display resolution to 1 Micro-Ohm, where M1 is 10 Micro-Ohms. M1 display resolution is considered more stable than M1B.
