  FEATURES
● High quality Taut Band movement.
● Measures insulation(MΩ), continuity(Ω) and AC voltage.
● Instant operation is possible with a push button, convenient timer is
    provided with automatic power off after three to five minutes to save
    the battery power.
● LED (red) indication when testing insulation and continuity.
● Use of a high efficiency and accurate DC-DC converter.
● Most suitable for insulation resistance measurement of electrical
    household appliances, power line distribution and installation.
