Was shown two Z-4000's operating via the DCS remote and the Remote Commanders. While the display on Z4000 "A" RH and Z4000 "B" RH shows the same voltage, the actual output is off by nearly 5 volts. "B" actually has 18 volts output while "A" is only 13.5 volts. Is there any way to correct this? They are about 2 years old, purchased new. Will be back there next week.
Thanks
