BLUE K7214+ ESR meter circuit same as K7254, EVB & Dick Smith MKII ESR Meter

Product Description

NEW Blue K7214+ ESR Meter classic circuit same as Blue ESR Meter, EVB ESR Meter, Dick Smith MKII ESR and Low Ohms Meter with translucent blue case

Please note: The picture is just to show the measurement result. The package does not include any batteries.

This K7214+ ESR METER is based on the famous BLUE ESR METER classic circuit, using a new low-power MCU to replace the original ZILOG Z86E0412 microprocessor, a new design of firmware, in addition to the original BLUE ESR METER all the functions, you can test hook zeroing data saved to the microcontroller EEPROM, so you do not have to do zeroing operations every time you turn on the computer.

You can set the automatic shutdown time of the meter, and the shutdown can indicate the battery voltage, the battery life is much higher than the model using ZILOG Z86E0412 microprocessor. Red ultra-high brightness LED display, measurement results can be displayed more clearly.

Note:Blue ESR Meter has been popular since 2007. This is the latest Bob Parker design and successor to the famous Dick Smith MKII ESR and Low Ohms Meter. This handy and cost-effective meter, can measure capacitor equivalent series resistance (ESR) in the circuit. ESR is a very important quality and performance characteristic of capacitors greater than 1uF. This meter makes quality measurements which are usually not possible to check with capacitance meters.
