My Weigh x RAW Tray Scale User Manual

My Weigh x RAW Tray Scale

Thank you for purchasing the My Weigh® × RAW TRAY SCALE. Please read all operating instructions carefully before use. This electronic scale is a precision instrument. With normal care and proper treatment, it will provide years of reliable service. For more information please visit www.myweigh.com. Never load the scale with more than the maximum capacity. Although the My Weigh® × RAW TRAY SCALE is designed to be extremely durable with extra overload protection built into the case, overloading will permanently damage it! Avoid any exposure to extreme heat or cold, your scale works better when operated at normal room temperature. Keep your scale in a clean environment. Dust, dirt, moisture, vibration, air currents and/or a close proximity to other electronic equipment can all cause an adverse effect on the reliability and accuracy of your scale. Handle with care. Gently apply all items to be weighed onto tray top. Avoid shaking, dropping or otherwise shocking the scale. Scales are delicate instruments and unlike cellular phones, scales have delicate sensors that determine how much an item weighs. If you drop or shock your scale, these sensors “feel” the shock and are sometimes destroyed. This happens with all digital scales. We design our scales to be as resistant to shock or drops as possible, however there is no way for us to protect 100% against load cell or sensor damage. Failure to follow these instructions will void your warranty. Always allow the scale to acclimate to normal room temperature for at least one hour before use. Give your scale sufficient warm up time. Usually 30-60 seconds before calibration to give the internal components a chance to stabilize.

PRECAUTIONS BEFORE USING THE BALANCE

1. Matter charged with static electricity can affect accuracy. Discharge all static electricity. For example, one method is to use Static-Guard spray, and spray it on both sides of the weighing platform.
2. The balance must be in an exact horizontal position in order to achieve accurate measurement results.
3. Don’t put any objects on the platform before powering on.
4. When possible please allow the scale to warm up for several minutes before operation.
5. Items should always be placed on the center of the platform when being weighed.
6. For optimum accuracy, recalibrate before each use.

BATTERIES

Low Batteries & bad battery connections are the #1 cause of scale malfunction and inaccuracy! We test all of our scale returns from consumers and 60% of them are battery related problems. This sounds silly but it’s true! A scale will perform poorly when it has low batteries. Use good quality batteries & replace them often (Remove the batteries if you plan to store the scale for longer than 14 days. We recommend using only good quality batteries with all of our scales. If your scale simply won’t turn on while on battery power, it is often caused by loose battery connections. Battery prongs (terminals) are made of metal and they have to be in contact with the batteries. You can use a paperclip to slightly bend the battery prongs to have a better connection. Some poorly designed batteries have recessed or partially obstructed battery terminals. This may cause your prongs to touch the plastic housing of the battery instead of the metal of the battery terminal.

Battery installation

• Press and lift open the battery cover located at the bottom of the unit
• Insert the batteries and make sure the polarity is correct (+) and ( -).
• Close the battery cover until it dicks shut.

OPERATION INSTRUCTIONS

Weighing Procedures

1. Press to turn on the scale. Wait until “O’ is displayed.
2. Press [UNIT] to select a weighing unit g, dwt, oz, ozt, 1/4 oz, 1/8 oz.
3. Verify the reading is “O”. Place objects on the weighing platform to weigh. When the reading becomes stable, the stable indicator is displayed.

TARE
Tare can be used for eliminating the weight value of an empty container. Place an empty container on the scale and press Then place the items to be weighed in the container.

NOTE: When all weight is removed from the weighing tray, the tared value of a container will be displayed as a negative number. Press again to return the scale to zero.

CALIBRATION
You must have an accurate 500g weight or combination of weights in order to calibrate. Calibration may be required when the scale is first set up for use, or if the scale is moved to a different altitude or new location. This is necessary because the weight of a mass in one location is not necessarily the same in another location. Also, with time and use, mechanical deviations can occur.

1. Press to turn on the power. The display will show “Hi” and then “—-“.
2. Press [UNIT], while “—-” is visible, the display will show “CAL” followed by an A/D value. Press [UNIT] again the display will show the required calibration weight.
3. Place the correct calibration weight on the platform. The display stops flashing once the calibration process has been complete.

SCALE FEATURES

• Auto Off/ Backlight Setting

An auto shut off feature is provided to conserve battery power. The scale will automatically turn off after 2 mins of inactivity.

To turn off/on the auto off & backlight follow these instructions:

1. Press and hold [UNIT and power on the scale with , then release both keys.
2. The display will show A ON (Auto off enabled) or A_OFF (Auto-Off disabled). Press [UNIT] to toggle and to confirm.
3. The display will show L ON (backlight enabled) or L OFF (backlight disabled). Press (UNIT] to toggle.
4. Press and hold for 3 seconds to confirm your settings  and turn off the scale.

ERROR MESSAGES

• : Low Battery
• Err-0: Overload
• Err-Z: Exceed zero track range turn on the power
• Err-S : The scale is unstable when turn on power
