basic information
*Features* 1. Records and displays the surge current level that has entered grounding lines, along with the detection time. This is useful for verifying the effectiveness of SPDs (surge protective devices) and for maintenance. 2. Data is recorded on an SD memory card. Since it is recorded in text format, it can be displayed on a computer without using dedicated software. 3. Outputs contacts during surge current detection and SPD degradation detection (a contact for 1 second). 4. Complies with RoHS regulations (only for OLR-31P).
