To be sure, a circuit tester is a very useful device capable of
measuring voltage, current, resistance, and various other
electric and electronic quantities. Accordingly, the object
of me'asurement coversvaries widely from minute current

to high voltage. Furthermore, the input impedance changes
from a few ohms up to high megohm level with the
measurement range cut over. These properties of a circuit

self off danger and damage to the meter. Especially when
checking high power equipment, no operation mistake
should be committed. Remember a circuit tester needs
periodical inspection and calibration to maintain it in good
condition. A tester known to be defective, or laid away
unused for many months must not be used to measure a
voltage above 100V. Be certain for a tester to undergo
