SEW insulation tester 4103

The 4103 insulation tester is characterized not only by rare measurement capabilities, but also, thanks to a special, highly durable housing, can be used in extremely harsh conditions, and are simple and safe to use. The construction of the testers uses the latest digital technology. All functions of the device are controlled by a special microprocessor made with CMOS technology, the constant measurement voltage is produced by a transistor converter, and the calibration data are stored in a non-volatile EEPROM memory. Measurement results, warning messages and other measurement data are displayed on a two-row liquid crystal display (maximum display of 6 digits), and operation of the instrument is facilitated by an interactive on-screen menu.

• Four insulation resistance measurement voltages
• Automatic range change
• ENER-SAVETM mode
• Analog bar graph indicating during the test the rise and fall of the external voltage present on the object under test or in the circuit
• Audible warning indication and display of a warning message in case of the presence of an external voltage on the object or circuit under test
• Overload protection
• Indication of low battery voltage (supplying the tester)
• Measurement of insulation test duration
• - Control by high-speed processor
• Automatic power off
• Compact instrument design and light weight
