Cum calibrez un multimetru digital M890D mai vechi

✔️Hello! In this video I calibrated as much as possible an older digital multimeter "M890D". For me, this one has more sentimental value. Because it was among the first digital multimeters purchased. ✔️For other videos on the same topic about calibrating various devices, I have attached links below: ►How to calibrate voltage and current on the XY-SK150S module:    • Cum calibrăm tensiunea și curentul la modu...   ►How to use and calibrate a 0.36inch 4-digit digital panel voltmeter:    • Cum utilizam si calibram un voltmetru digi...   ►We test a BM730 panel voltmeter, ammeter and wattmeter / Accuracy and calibration of the device:    • Testam un voltmetru, ampermetru si wattmet...   ✔️Contents: 00:00 - Introduction 00:25 - Multimeter disassembly and semi-adjustable position change 05:38 - DC voltage calibration 07:34 - DC current accuracy 08:36 - Capacitor measurement calibration 13:05 - Resistor measurement accuracy 14:22 - AC voltage accuracy 14:49 - AC current accuracy 15:36 - Gain factor ("hFE") measurement accuracy 17:01 - Diode mode measurement 17:54 - Diode mode voltage and current measurement 18:29 - End
