Features

• Automatic range selection: The UT511 automatically selects the correct measuring range for the insulation resistance being tested. This saves time and prevents errors.
• Data logging: The UT511 can store up to 100 test results. This is useful for troubleshooting problems or tracking the performance of electrical equipment over time.
• Polarization Index (PI) measurement: The PI measurement is a measure of the quality of the insulation. A higher PI value indicates better insulation.
• Dielectric Absorption (DAR) measurement: The DAR measurement is a measure of how quickly the insulation recovers after being subjected to a high voltage. A higher DAR value indicates better insulation.
• Low battery indication: The UT511 will display a low battery warning when the batteries are running low. This allows you to replace the batteries before they run out and the instrument stops working.
• Auto power off: The UT511 will automatically power off after a period of inactivity. This helps to conserve battery power.
• LCD display with backlight: The UT511 has a large LCD display with a backlight. This makes it easy to read the display in low-light conditions.
• Over range warning: The UT511 will display an over range warning if the insulation resistance being tested is outside the instrument's measuring range. This prevents damage to the instrument.
• High voltage indication: The UT511 will display a high voltage indication when the test voltage is above 1000V. This helps to prevent accidental contact with the high voltage leads.
