I recently got myself a PM 300 power analyzers, but my unit has a weird fault on what seems to be on channel 3 only.
If I go into the menu and select the single phase, two-wire mode, I can select to display one channel at the time with the DISP button, but as soon as I toggle to all three channels or channel three, the display shows only an error message: “CURRENT OVERANGE” (not a typo). If I toggle to default setting with the PROG key (red LED off) the display will only show this error message.
I have messed around with almost all settings especially the Inrush Current settings but to no avail. I have not changed anything in the calibrate menu since I do not have or have access to the equipment required to calibrate this instrument.
Is there anyone out there that has seen this error message before or have any suggestions, I would really appreciate it!
I have attached some “screen shots” to show the error. sorry for the poor picture quality, hopefully you will be able to make out the info.
