The following warning messages are given to prevent accidents resulting in injury or death owing to burns, electric shock or other. Be sure to observe these instructions along with the ones included in this instruction manual.1. Do not use the PC20TK with any power line exceeding 6 kVA.2. Be careful about voltage of 33 VAC rms (46.7 Vpeak) or 70 VDC minimum because it is dangerous to the human body.3. Do not input any signal exceeding the maximum rated input value.4. Do not try to measure a line (e.g., to a motor) where induced voltage or surge voltage may occur, because the maximum overload input value might be exceeded.5. Do not use the PC20TK if its main body or test lead is damaged or broken.6. Do not use the PC20TK with its case removed.7. Do not use any substitute for a fuse or connect wire for non-electrical use.8. During measurement, do not hold any portion of the test pin beyond the test lead.9. Do not input voltage to the current measurement connector. Inputting voltage to that connector will result in a short-circuit, blowing out the built-in fuse. However, this may involve a danger.10. Do not change over to any other mode during measurement.11. Ensure that you have selected the proper range and mode for each measurement run.12. Use the specified type (TL-21) of test lead.13. Do not try to make a measurement with the PC20TK or your hand being wet.14. Use the PC20TK indoors.15. Check the appearance and the display of each mode (range) at least once a year.
Warning
The PC20TK is not provided with an automatic power-off capability. Be sure to turn OFF the Function switch after measurement has been finished, because the batteries will otherwise run out earlier.
Caution
Prior to the assembling of the PC20TK, check the parts in accordance with paragraph (2) in "4-5 Preparations for assembling."

[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.
