6 Troubleshooting
If using long cable runs on the remote (greater than 100 feet) or if the
meter seems inaccurate, remove the jumper located below the voltage
configuration pins on the circuit board on the back of the unit. This dims
the LCD backlight, reduces power consumption, and improves meter
accuracy.
See the Owner’s Manual for the C-Series Multifunction DC Controller
for additional information about Troubleshooting.
