The IDEAL 1000A Clamp Meters with TightSight™ Display are versatile instruments designed for electrical measurements, offering enhanced safety features and user-friendly operation. These meters are available in two models: 61-772 (true RMS sensing) and 61-774 (true RMS sensing, measures DC current and capacitance).

Function Description:

The clamp meters are primarily used for measuring AC/DC current, AC/DC voltage, and resistance. They also feature audible continuity, capacitance measurement (61-774 model only), and frequency measurement. A key safety feature is the visual and audible indication when voltage is present, even if the meter is set to the wrong function. The TightSight™ bottom display allows for easy viewing of current measurements in tight locations, while the main display shows numerical values and units of measure for all other functions.

Important Technical Specifications:

Displays: 3-3/4 digit LCD with 4000 counts for both main and TightSight™ displays.
Backlight: Green illumination with auto-off after 4.5 minutes. The TightSight™ display only lights in Amp function to conserve battery.
