Electronic Specialties’ newest test instrument, model 582 Deluxe DMM with Amp Shutters, features a unique system of Amp Shutters that block the unused test lead jacks. The amp shutters prevent mistake operation, reduce blown fuses and greatly improve user safety.
How the Amp Shutters Work
When you go to move the DMM test function from voltage to amps, the function selector dial is blocked and it won’t move to the Amps function until you remove the red test lead from the V jack.
Once removed, the shutter swings up inside the DMM and then the Amps jack is opened up. Then the red test lead can be pushed into the Amp jack. Only after the red test lead is removed from the V jack can the operator then switch the DMM to the Amps function.
More Features
The 582 also features a fused 20-amp test range in both DC and AC. This higher testing range can be quite desirable for some technician applications. Most DMMs’ maximum amp test range is 10A, so the 582’s higher 20A range can be an important buying consideration.
Among other notable features are the highly visible, extra-large 2” digits with backlighting. The large size of the 2,000-count LCD display makes the numbers legible from across the room. This DMM also has a Data Hold function and built-in temperature readings in both F and C, with a temp probe included.
Testing Functions:
– DC/AC Volts
– DC/AC Current
– Resistance
– Frequency
– Capacitance
– Temperature F & C
– Audible Continuity
– Diode Test
The 582 has 10 Meg/Ohm input impedance, so it is safe to use on any automotive electrical system. This tester is fuse and overload protected and comes with a one-year warranty.
The unit comes with 40” test leads, temperature probe, installed battery, zippered carrying case and instruction manual.
