Category:DMM

Description:
Speedy Performance of Professional Testing - Two Models Provide High Accuracy and Fast Response



•60,000 count, 5-digit display, high-resolution measurements

•±0.025% DC V basic accuracy, wide 20 Hz to 100 kHz AC V frequency characteristics

•Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)

•Includes multiple measurement functions such as DC+ACV, temperature, capacitance, and frequency

•Includes terminal shutter mechanism for accident prevention (prevents erroneous test lead insertion)

•Measures large currents with optional clamp probe (only for DT4281, which has no 10 A terminal for accident prevention)

•USB communications function supports PC measurements (optional)

•Broad -15 (5°F) to 55°C (131°F) operating temperature range
