Product Overview
This single-pole voltage detector FL-I from HORSTMANN is a battery-free measuring instrument for verifying the presence or absence of voltage on a single conductor. The device has no internal power supply and no automatic self-test; visual indication occurs via LEDs and indicates either "voltage present" or "voltage not present". The FL-I is available in several voltage versions, and the model supplied is the 10 kV version (item number 50-1201-002).Function and Use
- Single-pole voltage detection without built-in power supply.
- Visual indication via three red LEDs.
- Before use: perform a functional test on a known voltage source, as the device does not have self-test.
- Place the detector's contact electrode directly on the conductor to be tested; the contact point must be bare metal or made accessible with a test probe through paint, if necessary.
Typical Applications
- Voltage testing on a single pole when verifying the presence or absence of operating voltage — performed by placing the contact electrode on the conductor to be measured, immediately after a successful functional test on known voltage.
- Use under dry, usually indoor conditions as indicated by the manufacturer.
