Safety Precautions

CAUTION : Read all safety warnings before installing, making connections, or servicing this equipment. Failure to comply with these warnings could result in personal injury and/or property damage. Retain all instructions for future reference.

Verify that the AC adapter’s input voltage range and plug type are compatible with the local ACmains power supply.
Position the instrument such that the AC adapter can be easily disconnected from the wall socket.
Position the power cord so that it does not pose a potential obstacle or tripping hazard.
Operate the equipment only under ambient conditions specified in these instructions.
The equipment is for indoor use only.
Do not operate the equipment in hazardous or explosive environments.
Only use the equipment in dry locations.
Only use approved accessories and peripherals.
Disconnect the equipment from the power supply when cleaning.
Service should only be performed by authorized personnel.

Intended Use
Use the instrument exclusively for weighing as described in the operating instructions. Any other type of use and operation beyond the limits of technical specifications without written consent from OHAUS, is considered as not intended. This instrument complies with current industry standards and the recognized safety regulations; however, it can constitute a hazard in use. If the instrument is not used according to these operating instructions, the intended protection of the instrument may be compromised and OHAUS assumes no liability.

**IR Sensor ***| IR Sensors can be programmed to act as a “touchless” button. See the User Menu section 4.3 for the available settings.

The IR Sensors can be activated by a hand or other object that is placed about 12mm (½ inch) above the sensor location. The sensor activation distance will vary based on the reflective nature of the object. If unwanted activations occur due to unique situations the sensor can be turned off. *Availability of IR Sensor is dependent on model and region.

INSTALLATION

Transportation Lock
The Transportation Lock is located under the balance. Rotate the pointer to the unlocked position

Location
Use the balance on a firm, steady surface. Avoid locations with excessive air current, vibrations, heat sources, or rapid temperature changes. Adjust the leveling feet so the bubble is centered in the circle.

Power
The AC Adapter is used to power the balance when battery power is not needed.

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
Balances with the optional rechargeable battery will need to be charged for 12 hours before the balance can be operated on battery power for the first time. 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 install C cell batteries, reference the Recharging 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

Note:
After power on, it is recommended to warm up the balance for at least 5 minutes before using it. Availability of IR Sensor is dependent on model and region.

Initial Calibration
When the balance is first installed it should be calibrated to ensure accurate results. Press and hold Menu-Cal until [mMeNU] (Menu) is displayed. When the button is released, the displaywill display [.C.A.L.]. Press Yes to accept, [SpaN] will then be shown. Press Yes again to begin thespan calibration. [–C–] blinks while zero reading is stored. Next, the display shows the calibrationweight value. Place the specified calibration mass on the pan. [–C–] blinks while the reading isstored. The balance returns to the previous application mode and is ready for use

OPERATION

All modes except for weighing must be activated in the User Menu before they are available, see Section 4.

Weigh Mode

Press and hold Mode until [wJeIGH] (Weigh) is displayed.
If required, place an empty container on the pan and press Tare.
Add material to the container. The display shows the weight of the material

Parts Counting Mode
This mode counts large numbers of items based on the weight of a reference count.

Place an empty container on the pan and press Tare.
Press and hold Mode until [Count] (Count) is displayed. [CLr.APU] (Clear Average PieceWeight) will then display.
Press No to use the stored APW. Proceed to step 6.
Press Yes to establish an APW. The balance will then display the stored sample size, i.e. [Put10]. Press No or Back to toggle the choices (5, 10, 20, 50 or 100).
Put the indicated number of pieces on the pan then press Yes to calculate the APW. Thedisplay shows the piece count. Note: Press Function to view the current APW.
Add additional pieces until the desired count is reached.
To clear the stored APW press and hold Mode until [Count] is displayed. Press Yes when[Clr.APU] is displayed.

Percent Mode
This mode measures the weight of a sample as a percentage of a reference weight.

Place an empty container on the pan and press Tare.
Press and hold Mode until [Percnt] is displayed. [Clr.ref] (clear reference) will then display.
Press No to use the stored reference weight and proceed to step 6.
Press Yes to establish a new reference. Balance will now display [Put.ref].
Add the desired reference material to the container. Press Yes to store the reference weight.The display shows 100%.
Note : Press Function to view the current reference weight.
Replace the reference material with the sample material. The display shows the percentage ofthe sample compared to reference weight.
To clear the stored reference press and hold Mode until [Percnt] is displayed. Press Yeswhen [Clr.ref] is displayed

Checkweigh Mode
This mode sets low and high weight limits for portion control processes.

Press and hold Mode until [CHeCk] (Check) is displayed. [CLr.ref] (clear references) will thendisplay.
Press No to use the stored reference weight limits and proceed to step 5.Note: Press Function to view the low and high reference weight limits.
Press Yes to establish new reference values. The balance will then display [Set. Lo]. PressYes to view the “Low” limit value. Press Yes to accept or No to edit the “Low” limit value. Thestored value then displays with the first digit highlighted [000.000 kg]. Repeatedly press Nountil the desired number appears. Press Yes to accept and highlight the next digit. Repeat untilall the digits are correct. Press Yes to accept the “low” limit value, [Set. Hi] will be displayed.
Repeat the same procedure to accept or edit the “high” value.
Place sample material on the Pan. The “Accept” indicator will now show that the sample weightis within the acceptable range.
To clear the stored reference values press and hold Mode until [CHeCk] is displayed. Press Yeswhen [Clr.ref] is displayed.

Verified weighing instruments in the EU
When the instrument is used in trade or a legally controlled application it must be set up, verified and sealed in accordance with local weights and measures regulations. It is the responsibility of the purchaser to ensure that all pertinent legal requirements are met. Weighing Instruments verified at the place of manufacture bear the following supplementary metrology marking on the descriptive plate

Weighing Instruments to be verified in two stages have no supplementary metrology marking on the descriptive plate. The second stage of conformity assessment must be carried out by the applicable weights and measures authorities. If national regulations limit the validity period of the verification, the user of the weighing instrument must strictly observe the re-verification period and inform the weights and measures authorities. As verification requirements vary by jurisdiction, the purchaser should contact their local weights and measures office if they are not familiar with the requirements.
