TM-6002   Battery Impedance Meter

 

• Measuring method：Impedance (AC four-terminal method).
• A/D conversion: Dual slope method.

 

Application

• TM-6002 is an ideal tester for automotive, UPS maintenance and telecommunication applications.
• Quick response time.
• Simultaneously display the results of battery Impedance,voltage measurements.
• Built-in comparator function to rate the conditions as pass,warning or fail.

Features

• The Battery Tester is designed for measuring the internal impedance and open circuit voltage of the secondary battery including Nickel-metal hydride battery ( NiMH),Nickel-cadmium battery(NiCd),Lithium-ion battery(Li-ion), Alkaline battery and lead-Acid battery.
• AC four-terminal method to measure the internal impedance by eliminating lead impedance and contact impedance to get the accurate results.
• Multi-display to show the internal impedance, voltage and clock of the battery simultaneously.
• It has 99 sets of composite comparator function, which can be set at impedance and voltage values to get the reliable detection of battery deterioration.
• Pin type leads, which can easily contact the battery electrodes supplied as standard to get more accurate 4-terminal measurement.
