Chapter 2. Initial Setup
12 Transport® Model PT878 Portable Liquid Flowmeter User’s Manual
2.3 Powering ON and OFF
To operate the PT878, the power cord must be plugged into line voltage or
the battery must be charged as described previously.
IMPORTANT: For CE compliance, the PT878 is classified as a
battery-powered device, not to be used with the AC adapter.
To comply with CE certification, do not operate the meter
with the charger plugged in.
To turn the PT878 on, press the red button in the upper-right-hand corner of
the keypad. Immediately upon power up the PT878 emits a short beep and
displays a “PCI Loader” message. It then validates the instrument
programming, and then displays the GE logo and the software version and
emits a long beep. If the meter fails any of these tests, contact the factory.
WARNING! If the meter fails the backup battery test, you must send
the unit back to the factory for a battery replacement.
Make sure you keep the batteries charged until you are
ready to ship the unit back to the factory. Before shipping,
print out all the log and site data, or transfer it to your PC.
