Introduction ST2822 series are designed for measuring inductance, capacitance and resistance components. The instrument can be powered by a 9V battery or external power adapter. The meter is not only applicable to the application occasion of bench meters but also conveniently used in the flow inspect and handheld measurement occasions. ST2822 series provide the primary parameter of up to 40,000 readings, secondary parameter of 0.0001 reading resolution, the maximum measuring frequency of up to 100kHz, constant internal resistance of 100Ω and testing level of 0.6Vrms. The auto range can rapidly...

Use with improper power adapters may damage instrument. NOTE: Internal battery supply will be automatically cut off since the normal supply of external power. If the battery is rechargeable (ST2822C), the external power will charge the battery simultaneously. ST2822C is installed an independent charging controller---charging control is still done even at the state of power-off. WARNING: Before connecting an external power adapter, be sure that the polarity matches the (+) and (-) labels as indicated inside the battery compartment. If it is not installed correctly and connected to an external...

Front Panel Buttons With the exception of the power button, all front panel buttons have specific colored labels on them. They are all marked in black, blue, or orange color. Each color has a specific representation, as described below: Black—the primary function，meaning that function will be set or configured upon pressing it. Orange—the secondary function, it means that the function will be set or configured if that button is pressed and hold down for 2 seconds. Blue—the utility function, the function will be set or configured if the UTIL button is pressed and hold down for a long time. See...
