[2] Using the PC20TK
2-1 Intended uses and features
1. The PC20TK is a kit for a general-purpose digital multimeter (DMM), which has been designed for
educational uses. Once assembled, it may be used as a normal small-capacity DMM for low-
voltage measurements.
2. The PC20TK features the auto mode that automatically selects an appropriate measurement range
in accordance with the measured value. It may also be used in the manual mode (measurement
range fixed or manually selectable) that allows for faster measurements.
3. The PC20TK allows the user to measure electric capacitance of a capacitor, which is often used
with a resistor as a circuit component.
4. The current measurement connector is provided with a safety cover that prevents the user from
inserting a test lead into it by mistake.
5. If you connect the PC20TK to your PC by using the optionally available PC link (software) and PC
link cable, changes in electric quantity can be displayed as values or graphs on the PC monitor.
