Thank you for viewing the American Weigh CM-500 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. Overloading your scale can permanently damage it!
• Avoid exposure to extreme heat or cold. Scales perform best at normal room temperature. If temperatures have changed dramatically, calibration adjustment 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 computers, cash registers, and cordless phones.
• Always weigh on a flat 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 first if you are having any trouble with your scale. This simple step can remedy most scale issues.
• Do not disassemble your scale. This product contains no user serviceable parts.
I. Part List
1. Scale
2. User Manual and Terms and Conditions
3. Mug (3 Sections)
4. CR2032 Lithium Battery (x1)
II. Key Description
The button on the left of the display marked ON/T is to power on and off the scale and to tare the scale to zero.
The button on the right of the display is the Mode key to swithc between the Units: g (gram) oz (ounce) ozt (troy ounce) dwt (pennyweight)

III. Battery Installation
1. Before using the scale for the first 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. Install the Battery Positive Side Up
Uses one CR2032 Button Cell Battery
IV. Operation
1. Place the scale on a flat, level surface and press the ON/T 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.
V. Changing the Unit of Measure
1. Press the MODE key to change the scale’s displayed unit of measure.
2. If the scale is turned off, then back on, it will default to the last unit used.
• CM-500 Units: g (gram) oz (ounce) ozt (troy ounce) dwt (pennyweight)
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.
1. Place the empty container or vessel on the weighing platform.
2. Press the ON/T key once. The display will then reset to zero. If the container is removed, it’s weight will be displayed as a negative number.
3. You may now fill 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 ON/T key again to re-zero the scale.
VII. Calibration
Calibration and adjustment are performed at the factory. However, the weighing range can shift slightly during 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 info below), adjustment is required.
Model: CM-500, Acceptable Tolerance (±): 0.2g,
Calibration Weight: 500g, Recommended Accuracy Class: OIML M2

VIII. Calibration Adjustment
1. With the scale off, press and hold the MODE and ON/T keys at the same time until the display shows a random number then release.
2. Press the ON/T key again and the display will flash "AL_F" followed by "500.0g".
3. Place a 500g calibration weight (not included) onto the weighing platform,
4. Once the weight is stable, press the ON/T key once more and the display will show "AL_F" and return to normal weighing mode. Calibration is complete.
IX. Troubleshooting
• Problem: Scale will not turn on
• Solution: Check the battery
• Problem: Displayed weight fluctuates randomly
• Solution: Make sure your workspace is stable and free of any air currents or vibration
• Problem: Displayed weight is inaccurate
• Solution: Perform a calibration adjustment
X. Error Codes
1. OUTZ - Zero range has shifted. Perform calibration adjustment. If the problem persists, the load cell may be permanently damaged due to overloading.
2. O-LD - Maximum capacity exceeded. Remove the extra weight to avoid damaging the load cell.
3. LO - Batteries are low. Replace the batteries.
