Amprobe AM-150 TRMS Digital Multimeter with optical PC connection had TRMS measurement and optical isolated PC interface capabilities, as well as auto and manual ranging. For most applications, the TRMS version of the multimeter is recommended in order to avoid large measuring errors. If uncertain, always choose TRMS version to assure measuring accuracy for all your applications, since it assures accurate measurements no matter what the signal strength is.
