EDL's MOV-1 Megaohm Validator provides a simple method of ensuring that insulation resistance testers are operating properly and within specification. Measurements performed in the field can cause the user to question the validity of the measurement results. This handheld device, housed in a protective case, allows the user to validate test equipment on site under the same, and sometimes harsher, ambient conditions. It provides six high-voltage capable resistant values (1M to 10G) with accuracy and stability. TechniCal Systems
