7. Measurement
7-1 Power ON
Confirm that the batteries of the main body of the Proximity Exhaust Noise Measurement
System and the operation part (wireless) are fully charged.
1) Battery built in to the main body of the Proximity Exhaust Noise Measurement System.
For the built-in battery, confirm by the battery level indicator on the main body panel.
High
: Battery level is high and normal operation
is possible.
Medium : Battery level is getting lower. Connect
the system to AC 100 V and charge the
battery as soon as possible.
Low
: Battery level is insufficient. Charge the
battery before use.
* Remaining battery level right after the delivery or after long storage (for more than 1
month) will be very low. Charge the battery once a month for about 10 hours. (Battery is
needed even when the AC power is used.)
* Do not charge over 12 hours to prevent the battery life becomes shorter.
* When the remaining battery level becomes low, normal operation such as printing by the
printer cannot be made. In some cases, the main body will be re-set during the printing.
* To charge the battery, turn the power switch to OFF and use AC power. Charging with
the power switch ON will require long time for charging and full charge cannot be
achieved.
