IMPORTANT: To relieve any internal pressure and allow proper airflow

inside the scale, unscrew the two rear leveling feet slightly, then level

the scale accordingly. When cleaning the scale, the rear leveling feet

must be screwed in tightly to avoid entry of water inside the scale.

2.4 Power

2.4.1 AC Power

The AC adapter (included) may be used to power the scale when battery power is

not available. Remove the rubber seal in the back. Connect the AC adapter plug to

the input jack. Then plug the AC adapter into a properly grounded power outlet.

2.4.2 Battery Power

The scale can be operated on the internal rechargeable battery when AC power is not

available. The scale will automatically switch to battery operation if there is a power

failure or the power cord is removed.

Before using the scale for the first time, the battery should be fully

charged for up to 12 hours. During charging, the battery Indicator

displays the charge level (see Table 2-1), and the scale can be operated

during charging. The battery is protected against over charging and the

scale can remain connected to the AC power line.

Charge Status Indication Light Charge level

Off Fully Charged

Flashing Green 70 – 100 %

Flashing Yellow 40 – 70 %

Flashing Red 0 – 40 %

The scale can operate for approximately 60 hours on a fully charged battery.

During battery operation, the battery Indicator displays the battery status (see Table

2-2).

Accuracy not guaranteed

NOTE:

• Charging the scale must only be performed in a dry environment.

• Install the rubber seal securely to ensure the scale is protected when

operating in a wet environment.

CAUTION: Battery is to be replaced only by an authorized Ohaus service

dealer.

Risk of explosion can occur if replaced with the wrong type or connected

improperly.

Dispose of the lead acid battery according to local laws and regulations.

EN-5Valor 2000 Series Scales

2.5 Initial Calibration

When the scale is operated for the first time, a Span calibration is recommended to

ensure accurate weighing results. Before performing the calibration, be sure to have

the appropriate calibration weight.

Refer to section 4.2 for Span calibration procedures.

3. OPERATION

3.1 Turning Scale On/Off

To turn the scale on, press the ON/ 0/T Off button. The scale performs a display test,

momentarily displays the model/software version, and then enters the active

weighing mode.

To turn the scale off, press and hold ON/ 0/T Off button until OFF is displayed.

3.2 Zero Operation

Press the ON/ 0/T Off button to zero the weight display. The scale must be stable to

accept zero operation.

3.3 Manual Tare

Place a container on the weighing pan, then press ON/ 0/T Off. The display will

show a net value of “0”. To clear the Tare value, press ON/ 0/T Off with the pan

empty.

3.4 Changing Units of Measure

Press the UNITS/Menu button to display the next available measuring unit. Only

measuring units enabled in the Unit Menu will be displayed (refer to Section 4.4).

4. SETTINGS

The Menu allows the user to customize scale settings.

4.1 Menu Navigation

Press and hold UNITS/Menu button until MENU is displayed, then release it.

Press Yes to enter the displayed menu or press No to advance to the next menu.

4.2 CAL Menu

SPAN Perform Span calibration Yes or No.

LIN Perform Linearity calibration Yes or No.

NOTE:

• Ensure the appropriate calibration masses are available before beginning

calibration (see Table 4-1).

• Ensure that the scale is level and stable during the entire calibration

process.

• Calibration is unavailable with LFT set to On.

• Allow the scale to warm up for approximately 5 minutes after stabilizing

to room temperature.

• To abort calibration, power off the scale.

4.2.1 Span Calibration

Span Calibration uses two points to adjust the scale. The first point is the zero value

where there is no weight on the scale. The second point is the Span value where a

calibration mass is placed on the scale.

When SPAN is displayed, press the Yes button to access

the Span Calibration menu item.

The display flashes 0.

With no weight on the scale, press the Yes button to

establish the zero point.

The display shows --C-- while the zero point is

established.

EN-7Valor 2000 Series Scales

The display flashes the span calibration point. Place the

specified weight on the scale and press the Yes button.

To choose a different span point, repeatedly press the No

button to increment the selections. When the desired

value is displayed, place the specified weight on the scale

and press the Yes button.

The display shows --C-- while the span point is

established.

If span calibration was successful, dONE is displayed

and the scale exits to the active weighing mode and

displays the actual weight value.

4.2.2 Linearity Calibration

Linearity calibration uses 3 calibration points. The first calibration point is

established with no weight on the scale. The second calibration point is established

at approximately half capacity. The third calibration point is established at capacity.

The Linearity calibration points are fixed and cannot be altered by the user during the

calibration procedure.

When LIN is displayed, press the Yes button to access the

Linearity Calibration menu item.

The display flashes 0.

With no weight on the scale, press the Yes button to

establish the zero point.

The display shows --C-- while the zero point is

established.

The display flashes the mid calibration point. Place the

specified weight on the scale and press the Yes button.

The display shows --C-- while the mid point is

established.

EN-8 Valor 2000 Series Scales

The display flashes the full calibration point. Place the

specified weight on the scale and press the Yes button.

The display shows --C-- while the full calibration point is

established.

If linearity calibration was successful, dONE is displayed

and the scale exits to the active weighing mode and

displays the actual weight value.
