I had this in stored away for a while as the usefulness was limited without the ability to use some important features shown in the manual.
It doesn't have "long averaging", manual ranging or frequency sync location setup as shown in the manual. So, its useless with many modern stuff. Each time there's a pulse load, it goes blind and everything gets lost in range switching. For example, NiMH charger, laser printers, electronics in standby mode. Is there a way to enable this mode or does it need a new firmware? Can you email me the new firmware?
It's a V2.02, 1996 or so. Serial number is hand written and too faded to be legible. The old calibration service on former Voltech page showed how they adjust it even if calibration is within specs, and service includes update to newest software.
