TEST EQUIPMENT

Our compact, low cost Model MM-1 Digital Auto-Range Multimeter is ideal for general
electrical testing and troubleshooting. This full function multimeter measures DC and AC
voltage to 600 V, DC and AC current to 10 A and resistance to 400 Ω. In addition to volts,
amps and ohms, this meter includes audible continuity, diode, LED and transistor hFE
tests. The rotary switch allows you to select from any of the functions quickly and easily.
The 4 digit backlit LCD features value, mode, and low battery indication. The rugged, high
impact case is double injected for excellent strength and durability. The Model MM-1 is
furnished with black and red test leads, batteries and carrying case with belt loop.
