HABOTEST HT124A+ Smart Digital Multimeter,Battery Voltage Tester, 4000 Counts Smart Measurement,Auto-Ranging Voltmeter,Non-Contact DMM,Ohmmeter

The HABOTEST multimeters, available in two optional models - Type 1 (HT124A+) and Type 2 (HT124B+), offer distinct features.The HT124A+ model lacks capacitance measurement and diode test functions. In contrast, the HT124B+ model includes both capacitance measurement and diode test capabilities.Both models have a sleek black color and a durable ABS shell material. They are equipped with a 2.5-inch LCD screen that provides clear visual feedback. The count is set at 4000 counts, allowing for relatively precise measurements. The maximum voltage between terminals and earth ground is 600V, ensuring safety and proper usage within specified limits. The sampling rate is approximately 3 times per second, providing a reasonable update frequency for measured values.When the measurement exceeds the range, it indicates "OL". There is a low battery indication to alert the user when the battery power is running low. The input polarity is automatically shown with a "-" sign. These multimeters require 2 x 1.5V AAA batteries (which are not included).They are suitable for use in environments with CAT. III 600V, a pollution level of 2, and at altitudes less than 2000m. The working temperature and humidity should be within 0 - 40°C (< 80% RH, < 10°C non-condensing). For storage, the temperature and humidity range is -10 - 60°C (< 70% RH, with the battery removed). The temperature coefficient is 0.1 x accuracy/°C (< 18°C or>28°C).The multimeter without a protective case measures 12.5 * 6.5 * 2cm (or 4.92 * 2.56 * 0.79in) and weighs 140g (or 4.94oz). With a protective case, it measures 13 * 7 * 2.3cm (or 5.12 * 2.76 * 0.91in). These multimeters are reliable tools for various electrical measurement tasks, with the option to choose the model that best suits specific needs.
