功能

• The so-called "tester" (3999 count). It is the most basic measuring instrument for measuring voltage, current and resistance. Temperature measurement of up to 1000°C is possible, and a thermocouple is included as a sensor. Higher LDM-81B models with basic specifications can measure volume (4 nF to 100 μF range) and frequency (5 Hz to 30 MHz range) in addition to higher accuracy of up to 1999 count →3999 count.
• This is what we call a "tester." It is the most basic measuring instrument for measuring voltage, current and resistance. This product has basic specifications but can measure temperature up to 1000°C and comes with a thermocouple as a sensor. It can measure frequencies up to the 30 MHz range. It can also be used to measure the 555 oscillation frequency.
