Blade V2 Manual

Thank you for purchasing the American Weigh Blade

v2 digital pocket scale. Please read all operating instructions

carefully before use. Scales are precision measuring devices

and should always be handled with proper care. To ensure

years of reliable service, keep these simple tips in mind:

• Do not exceed the scale’s maximum capacity. This

scale has integrated overload protection, but any

overload protection has its limits.

• Avoid exposure to extreme heat or cold. Scales

perform best at normal room temperature. If

temperatures have changed dramatically, recalibration

may be necessary.

• Allow your scale to warm up for 30-60 seconds before

performing calibration (if available).

• Store your scale in a clean, dry location. Dust, dirt,

and moisture can accumulate on the weighing

sensors and electronics causing inaccuracy or

malfunction.

• Avoid using your scale in close proximity to strong

radio wave emitting devices such as cordless phones.

• Alwaysweighonaatandlevelsurface,freefrom

vibrations and drafts. The corner of a room is usually

the most stable.

• Gently apply all items to be weighed. Do not drop

items onto the weighing platform.

• Avoid dropping your scale. The warranty does not

cover damage due to rough treatment or overload.

• Checkthebatteriesrstifyouarehavinganytrouble

with your scale. This simple step can remedy most

scale issues.

• Calibration should be checked and adjusted

occasionally as part of routine scale maintenance.

I. Part List

1. Scale

2. Cover/Expansion Tray (top and bottom)

3. AAA Batteries (x2)

II. Key Description

1. Power Key - Turns the scale on or off.

2. Mode Key - Changes the displayed unit of measure.

Enters calibration if pressed during startup (see VII)

3. Tare Key - Re-zeros the scale. Used to remove the

weight of a tray or container.

4. Backlight Key - Turns backlight on or off.

III. Battery Installation

Proper Battery Installation

Blade V2 Manual

Low batteries can cause inaccuracies in digital scales. If

youareexperiencingissueswithyourscale,rsttrynew

batteries. Most times, this will solve the problem.

1. Beforeusingthescaleforthersttime,check

the battery compartment and remove any plastic

insulation strips or packaging that may be in place to

prevent battery drainage during shipping/storage.

2. If you are replacing the batteries, make sure the

positive and negative contacts are properly aligned.

IV. Operation

1. Placethescaleonaat,levelsurfaceandpressthe

key to turn the scale on.

2. Once the start-up process completes and the scale

goes to zero you are ready to weigh.

3. Place the quantity to be weighed onto the weighing

platform.

4. Wait a couple seconds for the display to stabilize

before taking a weight reading.

5. To turn the scale OFF, press the key again.

V. Changing the Unit of Measure

1. Press the Mkey to change the scales displayed unit

of measure.

2. If the scale is turned off then back on, it will default

to the last unit used.

• Blade V2 Units: g (gram) oz (ounce) ozt (troy

ounce) dwt (pennyweight) ct (carat) gn (grain)

VI. Using the Tare Feature

You can use this scale’s tare feature to subtract the weight

of an empty container or vessel for net weight determination.

NOTE: The weight of the container will subtract from the

available capacity (subtractive taring).

1. Place the empty container or vessel on the weighing

platform.

2. Press the Tkey once. The display will then reset to

zero. If the container is removed, its weight will be

displayed as a negative number.

3. Youmaynowllthecontainerwiththequantityto

be weighed. The display will show the net weight of

the contents.

4. To return to normal weight display (gross weight),

remove any items from the weighing platform and

press the T key again to re-zero the scale.

VII. Calibration

Initial calibration is performed at the factory. However, the

calibration can drift slightly due to stresses from shipping.

Also, due to changes in local acceleration of gravity around

the world, adjustment is recommended when moving the

scale from one location to another. To check calibration:

1. Place the required calibration weight on the scale

and note the displayed value.

2. If the displayed value is not within acceptable

tolerance (see chart on next page), adjustment is

required.

VIII. Adjustment

1. Press the key to turn the scale on, then immediately

press and hold the M key until “CAL” is displayed

then release.

2. PresstheMkeyagain.Thedisplaywillash“CAL”

followed by the required calibration weight (see

above).

3. Place the required calibration weight on the center

of the weighing platform.

4. Oncetheweightisconrmed,thedisplaywillshow

“PASS” then return to normal weighing mode.

NOTE: Adjustment using the incorrect mass will

result in inaccurate readings.

IX. Troubleshooting

• Problem: Scale will not turn on

• Solution: Check the batteries and battery contacts.

• Problem: Displayedweightuctuatesrandomly

• Solution: Make sure your workspace is stable and

free of any air currents or vibration. In some cases,

nearby radio wave emitting devices can cause

uctuations.

• Problem: Displayed weight is inaccurate

• Solution: Perform a calibration adjustment. If

you are still having trouble, contact our warranty

department.

X. Error Codes

1. OUTZ - Zero point has drifted out of the acceptable

range. Try to perform a calibration adjustment. If the

problem persists, the load cell may be permanently

damaged due to overloading.

2. O-Ld - Overload. The maximum capacity has

been exceeded. Remove the extra weight to avoid

permanently damaging the load cell.

3. Lo - Batteries are low. Replace the batteries.
