Product Overview
CT93-10A handheld DC resistance tester is mainly used for measuring DC resistance of small and medium-sized transformers, generators, motors, transformers, etc. The instrument is set with multiple current levels to meet various measurement needs. It is equipped with lithium batteries as standard to meet the needs of field measurements.
Advantage
◆High resolution 65K true color 7” touch screen with Chinese and English interface switching, high brightness, and clear display under strong light.
◆ The sampling instrument is powered by an internal battery or power adapter, making it convenient for outdoor operations.
◆Equipped with the temperature conversion function of copper and aluminum, it can convert the resistance values at different temperatures according to customer needs, facilitating data comparison.
◆ Digital management of power supply batteries, with functions such as remaining battery display, remaining battery alarm, and overcurrent protection.
◆ Equipped with non power-off data storage and a perpetual calendar, capable of storing 1000 sets of test data and storing test time in real-time.
◆Equipped with USB flash drive interface and printer expansion interface, optional external micro printer can print test data in real-time.
◆ Equipped with protection functions such as discharge sound alarm, power overheating, and voltage reversal.
◆ Maximum 10A measurement gear test current, convenient for measuring the low voltage side resistance value of large capacity distribution transformers.
◆ Optional Bluetooth module, which can connect Android system phones and tablet devices to achieve intelligent management and operation.
◆ On load switch can be directly switched in the measurement state, and the instrument automatically refreshes the data without resetting.
