2.4 Power
The AC Adapter is used to power the balance when battery power is not needed.
Connect the AC Adapter plug to the
input jack. Connect AC Adapter to the proper AC supply.
Battery installation (without optional internal battery):
Remove battery cover and install 4 batteries using the polarity indications as shown in the
compartment.
Optional rechargeable battery (NVL and NVT models only):
Balances with the optional rechargeable battery will need to be charged for 12 hours before the
balance can be operatedon battery power for the firsttime. The battery is protected from
overcharging so the balance can remain connected to the AC power.When the battery is fully
charged the battery indicator on the display will stop blinking.
To remove the rechargeable battery option and installC cell batteries, reference theRecharging
Battery Option instruction manual for step by step instructions as well as disposal instructions.
Caution: Risk of explosion can occur if the rechargeable battery is replaced with the
wrong type or if it is not properly connected.
2.5 Initial Calibration
When the balance is firstinstalled it should be calibrated to ensure accurate results.
Press and hold Menu until [mMeNU] (Menu) is displayed. When the button is released, the display will
display [.C.A.L.]. Press Yes to accept, [SpaN] will then be shown. Press Yes again to begin the span
calibration. [--C--] blinks while zero reading is stored. Next, the displayshows the calibration weight
value. Place the specified calibration mass on the pan. [--C--] blinks while the reading is stored. The
balance returns to the previous application mode and is ready for use.
