Iso-Tech IDM201N Instruction Manual

The Iso-Tech IDM201N is a versatile and portable bench-type multimeter suitable for workshop and laboratory engineers and technicians, as well as field-service engineers who require a self-powered instrument for maintenance, test, or repair activities. It can be powered by an AC mains supply or internal batteries. The instrument features a 3½ digit (2000 count) backlit LCD display, auto-range function, and a variety of measurement capabilities, including DC and AC voltages, DC and AC currents, resistance, continuity checking, capacitance, diode testing, and frequency.

Frequently asked questions

The IDM201N can measure up to 20A, but for currents greater than 10A the maximum measurement duration is 30 seconds in any 10 minute period.

Connect the BLACK test lead to the COM terminal and RED test lead to the "VΩHz" terminal. Set the rotary switch to the "Ω" position to measure resistance. Select Ω measurement using the function button.

Set the rotary switch to the "" position. Connect the BLACK test lead to “COM” terminal and RED test lead to the “VΩHz ” terminal. Connect the test leads across the diode and note the reading. Reverse the connections to the diode and again note the reading. If the diode under test is good, the test in one direction should show a voltage between approximately 0.40V to 0.80V for a silicon device and the test in the opposite direction should show ”OL”. A faulty device will show either “000”, “OL” or approximately 3.2V or a combination of these in both directions.
