UT502A
UT500 series insulation testers are used to measure the
insulation resistance of electrical equipment and household appliances. This is
done by measuring the insulation resistance between electrical circuits or
between circuits and ground. UT500 series can measure insulation resistance, AC
Voltage, low resistance, PI (Polarization Index) and DAR (Dielectric
Absorption). These are dieal tools for ensuring transformers, genera-tors, high
voltage motors, power capacitors, power cables, arresters and other electrical
equipment that can operate in a safe and accurate manner.
Applications:
It is used for insulation resistance measurement for
insulation materials and various kinds of electric equipment’s such as
transformer, electric machines, cables, switches, electrical appliance, a ideal
tool for electric maintenance, testing and inspection.
Features:
1. 2000 count LCD display, overload indication, backlight
2. AC voltage measurement, auto power off
3. Auto discharge
4. Continuous measurements mode, red warning light and
buzzer function
5. Continuous low resistance measurement
6. PI and DAR
measurement, auto resistivity calculation
7. Low resistance returning to zero function to improve
accuracy.
