DRM-20M DC Winding Resistance Meter
• With 20A maximum output current of test power supply and 0 ~ 25kΩ test range, this instrument can meet most transformers’ test needs.
• During test, this instrument can automatically calculate resistance change rate within 5S, 15S and 30S, which can assist testers to judge test data stability and prevent data misreading.
• It is equipped with multiple protection functions such as back electromotive force protection, open circuit protection and power failure protection.
• Equipped with a thermal printer, this instrument can store 200 pieces of data locally and support mass data storage in USB disks.
• With fresh and simple 7-inch industrial-level true color screen and integration of full touch control and jog dial, it provides comfortable and convenient human-machine interaction.
