🍭Welcome to the shop🍭 💎Characteristics💎 Logical probes are used to display logical level (high or low) and capture positive or negative pulses as short as 30 nanoseconds. Logical probes can be very convenient and accurate in measuring logic circuits.It is powered by the measured circuit. You can use the TTL/CMOS switch to select logical level (CMOS, TTL) to test logic. The red light indicates high logical level, the green light indicates low logical level, the yellow light indicates that the probe catches positive or negative pulse, and the switch is in MEM state. Please do not use testers around gasses, dust or steam to ensure safety. To avoid damage to the instrument, do not enter a voltage exceeding 40 V DC/V AC into the device. ✎Specifications✎ Power supply: 5-15V DC Power supply protection: 20V DC/V AC Maximum input voltage: 40V DC/V AC (duration < 15 seconds) Maximum input signal frequency: 20MHz Input impedance: 1m Pulse indicator flashing time: 500mS Working temperature: 0-40°C. relative humidity < 80% Storage temperature: - 20-50°C. relative humidity < 85% Material: plastic Color: black and red Weight: 121g/4.3 oz Size: 24x5.6x5cm/9.4x2.2x2in 📦Packing list📦 1x logic probe 2x user manual (english, chinese)
