IDEAL 61-357 / 61-347 Digital Multimeter Instruction Manual

Product Overview

The IDEAL 61-357 and 61-347 are auto-ranging True Root Mean Square (TRMS) digital multimeters designed for professional use. These meters measure AC and DC current, voltage, frequency, resistance, continuity, capacitance, and diodes using test leads. They also feature a K-Type thermocouple input for temperature measurement and a non-contact voltage (NCV) sensor for detecting live voltage between 40V and 600V AC.

Safety Information

Warning: Arc Flash and Shock Hazard. Proper Personal Protective Equipment (PPE) is required. Always follow NFPA 70E safety standards. Before use, inspect the meter and test leads for damage. Never use the meter if the case is cracked or if the leads show exposed metal. Ensure fingers are kept behind the tactile barrier on the probes during measurement. Always disconnect test leads from the circuit before opening the battery compartment.

Operation

The meters feature a rotary dial for function selection and a SEL button to toggle between sub-functions (e.g., AC/DC, continuity/resistance). The 61-357 model includes an analog bar graph for quick visual reference. The NCV function allows for non-contact detection of live conductors. Data hold, MAX/MIN recording, and relative (REL) measurement features are available to assist in complex testing scenarios. The meters are IP52 rated for dust and water resistance.

Maintenance and Service

Regular inspection of the meter, test leads, and thermocouple is essential for accurate readings. If the meter is not in use for more than one month, remove the batteries to prevent leakage. The meter uses two specific fuses for current protection: a 600mA/1000V fuse for the mA/uA terminal and an 11A/1000V fuse for the 10A terminal. Only use specified replacement fuses to maintain safety and performance. Clean the exterior with a damp cloth and mild detergent; do not use abrasives or solvents.

Disposal

This product must not be disposed of as unsorted municipal waste. It should be recycled in accordance with local regulations. Used batteries must be returned to authorized collection points to prevent environmental harm.
