[2] APPLICATION AND FEATURES
2-1 Applications
This unit is a highly sensitive tester designed for measuring electric circuits
having a small capacity. It can measure voltages at various areas of
compact communication equipment and household electric appliances,
voltages of lamp lines and various batteries, and micro current in the mA
class.
2-2 Features
This unit is a highly sensitive “FET electronic tester” having the DC
voltage function of which the internal resistance is as high as 2.5 to 12
M
Ω
, and also the DC current function with the 0.12 µA range.
The zero center meter (NULL meter) function facilitates measurement
of ± DC voltage and ± DC current.
The frequency characteristic of AC low voltage ranges (3 V and 12 V
ranges) is 40 Hz-1 MHz. The Vp-p value of triangular-wave, square-
wave over 20 % duty cycle voltages of waveforms can also be
measured at 3 V range.
