How to Use 1. Press the power button to turn on off the instrument. The meter will automatically calibrate when it is turned on, and it will display OL when it is finished, and it will automatically enter the resistance measurement mode. If it is not properly self calibrated, the meter will display the Er sign, which indicates that there is a power on error, and the common reasons for power on error are that the jaws are not closed well, or the wires are clamped into the jaws when it is turned on. 2. Automatically shut down after reaching the set shutdown time, the meter ProductSiteLaunchDate : 2025-05-15T09:53:29.273Z Size : One Size Style : VTSYIQI20250303145187654567VTSYIQI SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredHasProductIdentifierExemption : 1 UnitCount : 1 UnspscCode : 46191500
