The Multimeter Models 5231 and 5233 are rugged, economical TRMS digital multimeters with a nonelectrical contact testing (NCV) function for detecting live electrical circuits (the display turns red). These multimeters are designed for safety: IEC61010 600V CAT IV. The Models 5231 and 5233 provide a Volt, Ohm, Continuity and Diode function.
The Model 5233 also has a Capacitance, Frequency, Duty Cycle and Ammeter function. They both include an AC voltmeter function with low input impedance that is capable of finding ghost voltages by adding a burden to the circuit.
The Model 5231 performs AC/DC direct reading current measurements up to 600A with a current clamp accessory plugged in, while the Model 5233 can measure up to 10A directly and can measure temperature in both °C or °F using K-type thermocouples.
The rotary function switch provides two OFF positions (OFF and OFF NCV). While in the OFF NCV position, the display will turn red if placed close to a live cable, providing a safe and easy way to detect hot wires. These meters have a high sensitivity with a resolution of 0.01mV and can withstand overloads up to 8000V.
These multimeters are ideal for electrical installers, electricians and heating or air-conditioning specialists.
