2. Making a Measurement
2.1 Built-in Battery
The instrument can operate either from the built-in Ni-H rechargeable battery, which will last over 10 hours
of continuous operation when fully recharged, or from an external AC/power supply from the battery
charger. The battery charging circuitry utilizes both constant-current and constant-voltage. This allows fast
charging initially and then reverting to trickle charge when the battery nears the full recharge. Generally,
when the green LED starts to turn on, the battery is nearly 95% charged. When the red LED is off, the
battery will be 98% recharged.
Trickle charging ensures that over-recharging is never a concern. The charger can if fact remain
connected to the handset for tests or monitoring situations requiring more time than the standard battery
life.
A fully charged battery will show an internal battery terminal voltage of approximately 4.25V. The terminal
voltage and an approximate battery time remaining are displayed on window M07. Please note that the
estimator is not an exact indication of time remaining but only estimation. Use the Mains power supply for
long term testing. It is NOT advisable to run the system below a 3.0V level at the terminals.
2.2 Power Up Self-Check
Press the
ON
key to switch on the instrument and press the OFF to turn off the power. Once the flow
meter is switched on, it will run a self diagnostic program, checking first the hardware and then the
software integrity. If there are any issues, an error message will appear on the display. Table 3 in Section 5
on Troubleshooting will explain any errors and advise of corrective action.
Following the startup self-diagnostics, the flow meter will display Menu Window Number 01 (M01). This
windows displays the Process Velocity, the calculated Flow Rate, the Positive Totalizer (+), Signal Strength
and Signal Quality. All these values are based on the application parameters last configured in the AUF610
handheld.
The flow measurement program always operates in the background of the user interface.
2.3 Keypad
The keypad for the operation of the flow meter has 18 keys, as
shown by the diagram below. Keys 0

9
and the . key
are for entering numerical values.
The

menu window. They also acts as the+/-keys when entering
numerical values. The
key is for backspacing or when there
wants to move left or backspace the character that is located to
the left of the cursor. The ENT key is used to ENTER data or
inputting any selections.
The MENU
key (referred to as the M key) allows direct access
