7.3 Troubleshooting/Resetting the DG-700

If the DG-700 gauge locks up or otherwise appears to be displaying inconsistent readings, try the following steps to
reset the gauge.

Simply turn the gauge off for 5 seconds and then turn it back on (using the ON/OFF button).

If turning the gauge off and on does not take care of the problem (or you were unable to turn the gauge off), first
remove the batteries from the battery compartment. Once the batteries have been removed, hold down the
ON/OFF button for 10 seconds to fully discharge the gauge's internal electronic components. Carefully replace
the 6 AA batteries. Be sure to insert the batteries with the proper polarity (+/-) as illustrated on the inside of the
battery compartment. Turn the gauge back on.

If neither of the steps above takes care of the problem, you will need to send the gauge back to The Energy
Conservatory for servicing (see Section 7.1.b above).

7.4 AC Power Supply Specifications

The AC power input jack can be used with an optional AC power supply to provide a long term power source for the
gauge (to be used when data logging). The gauge is normally powered by 6 AA batteries located in the rear battery
compartment. When the AC power supply is plugged in, the power supply bypasses the batteries in the battery
compartment. Note: Always turn off the gauge before plugging in the AC power supply.
Universal Specifications for Power Supply: 100-240V/50/60Hz Input, 12VDC Output, Center "+", 12mm Barrel
Length, 3 W Min. Output (International mains adapters included).
