Craftsman Digital Multimeter 82082 User Manual -

Craftsman 82082 is a digital multimeter designed for basic electrical testing, such as measuring voltage, resistance, and current. Unlike some premium models, the manual-ranging

device, meaning you must manually turn the selector dial to the appropriate range for each measurement. Key Specifications and Functions

The manual identifies several primary measurement functions and limits: : Measures both AC and DC voltage up to a maximum of : Measures DC current up to

. High-current measurements (above 200mA) require moving the red probe to the dedicated and should not exceed 30 seconds. Resistance & Continuity

: Measures electrical resistance (ohms) and includes an audible continuity test to check if a circuit is complete. Diode Test : Used to check the functionality of diodes. Protection : The device is rated

and includes fuse protection for lower current ranges (typically up to 200mA/400mA). Safety Instructions

To prevent electric shock or damage to the meter, the manual emphasizes several critical rules: Input Limits craftsman digital multimeter 82082 user manual

: Never apply voltage or current exceeding the maximum specified limits (e.g., 600V for voltage). Switching Modes

connect the leads to a voltage source while the dial is set to resistance ( ) or diode mode, as this can damage the internal circuitry. In-Circuit Tests

: Always turn off power and discharge capacitors before measuring resistance. Operational Safety

: Never operate the meter unless the back cover is securely fastened. Sears PartsDirect Basic Operation Steps For common tasks like testing a 120V outlet: Lead Connection : Plug the black lead into the port and the red lead into the Range Selection

: Set the dial to a range higher than the expected value (e.g., the setting for a standard outlet). Measurement : Insert probes into the outlet. If the screen displays "

" (Overload), the value exceeds the current range and you must switch to a higher setting. Maintenance: Battery and Fuse Battery Replacement : The unit typically uses a 9V battery Craftsman 82082 is a digital multimeter designed for

. To replace it, remove the rubber holster, unscrew the back panel with a Phillips screwdriver, and observe correct polarity when inserting the new battery. Fuse Replacement

: If the meter fails to read current but voltage still works, the internal fuse may be blown. Access the fuse by opening the rear case and replace it only with a fuse of the same rating (often 250mA or 500mA depending on the exact sub-model). Digital Multimeter Rundown

Craftsman Digital Multimeter 82082 User Manual

The user manual for the Craftsman Digital Multimeter 82082 provides detailed information on how to use the multimeter safely and effectively. Here are some key points to keep in mind:

1. Introduction

The Craftsman 82082 is a portable, handheld digital multimeter (DMM) designed to measure electrical properties such as Direct Current (DC) and Alternating Current (AC) voltage, DC Amperage, resistance, and temperature. Housed in a rugged ergonomically designed casing, it is frequently favored for automotive diagnostics due to its auto-ranging capabilities and temperature probe integration. This manual aims to provide users with a structured approach to utilizing the device effectively while mitigating the risks associated with electrical testing.

5.2 Measuring AC Voltage

  • Set switch to V~ (200V or 600V range only – typical for this model).
  • Follow same lead connection as DC voltage.

4. Safety First: Essential Precautions

Warning: Failure to follow these guidelines can result in electric shock, injury, or damage to the multimeter.

  • Never exceed the rated voltage. The 82082 is typically rated for 600V AC/DC maximum.
  • Do not measure voltage when the dial is set to Resistance (Ω), Continuity, or Current (A). This can blow the internal fuse or destroy the meter.
  • Always start with the highest range if you are unsure of the voltage or current you are measuring.
  • Remove test leads before opening the battery or fuse cover.
  • Do not use the meter if the body or leads are wet. Moisture drastically reduces insulation resistance.
  • Inspect test leads regularly for cracks or fraying.

C. Resistance (Ohms)

  1. Black lead → COM. Red lead → VΩmA.
  2. Power off the circuit completely (no live voltage).
  3. Set dial to Ω (200, 2k, 200k, 2000k ranges).
  4. Touch probes across the resistor or component.
  5. If display shows "1" (OL), switch to a higher range.

Diode & Continuity Test

  1. Turn dial to the Diode/Symbol position.
  2. Continuity: Touch probes together. The buzzer should sound.
  3. Diode: Red probe to Anode (+), Black probe to Cathode (-). A good silicon diode reads 0.5V~0.8V forward; "OL" or "1" reversed.
