SAFETY PRECAUTIONS All safety messages are identified by the following, "WARNING" or "CAUTION", of ANSI Z535.4 (American National Standard Institute: Product Safety Signs and Labels). The meanings are as follows: WARNING CAUTION A potentially hazardous situation which, if not avoided, could result in death or serious injury. A potentially hazardous situation which, if not avoided, may result in minor or moderate injury. This manual is subject to change without notice at any time to improve the product.
Compliance with FCC rules Please note that this equipment generates, uses and can radiate radio frequency energy. This equipment has been tested and has been found to comply with the limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to provide reasonable protection against interference when the equipment is operated in a commercial environment.
Security slot AC adapter jack (Use a security cable commercially available.) (Use a correct AC adapter for your local voltage and receptacle type.) Battery indicator STABLE indicator NET indicator Weighing units ZERO indicator ON:OFF key RE-ZERO MODE key key Turns the scale power on/off. Sets the display to zero. When the weight is within ±2% of the weighing capacity to the zero point at the power-on, the key will zero the scale. When the weight exceeds +2%, it will be subtracted as tare weight.
Note The batteries provided with the scale are for testing the performance of the scale and may have a limited life. AC adapter When Using the AC adapter Step 1 Verify that the AC adapter is correct. Step 2 Plug the AC adapter into the AC adapter jack. AC adapter jack Possibility of Electrostatic Influence When the ambient humidity gets low, plastics and insulators will be easily charged. That may make the reading unstable and cause some errors.
Errors eeeeee ------ Overload. Remove object from the weighing pan. Out of range or unstable error. There is a load beyond the zero range at the power-on. When pressed the RE-ZERO key or powered on, unstable weighing shows this display either. Low battery. Replace batteries with four new ones immediately. Calibration error. Unstable weighing or incorrect calibration weight. Internal errors (# will be 1, 2, 3, 4, 5 or 6). Request service.
Automatic Power Off Function If the scale is left ON and the STABLE is displayed, the automatic power-off function turns power off after approximately 5 minutes. poff 0 poff 1 Automatic power off function is disabled. Automatic power off function is enabled. (factory default) Setting the Response/Stability Condition This function is to specify the response speed and to stabilize the weight value reducing the influence of ambient environment like vibration.
Setting the Weighing Units to Use The scale has the weighing units listed in the table below and the units to be used only can be selected. Set the weighing units enabled or disabled as appropriate. There are three types of taels, HK general/Singapore tael, HK jewelry tael and Taiwan tael. But one of them can be selected. The order of units to be displayed is as in the table and it cannot be changed. UNITS key To select the unit to be set. RE-ZERO key To set the displayed unit enabled or disabled.
CALIBRATION When is Calibration Required? Calibration switch Calibration may be required when the scale was initially installed or has been moved to another location. Calibration switch cover Calibration Using a Calibration Weight Step 1 Press the Calibration switch while the scale is in the weighing mode. Then, Cal will be displayed. Step 2 Press the RE-ZERO key and Cal 0g will be displayed. With nothing on the weighing pan, press the RE-ZERO key.
gravity acceleration of your scale to the value of the area where the scale is used. See “The Value of Gravity Acceleration at Various Locations” of this manual. Step 1 Start from Cal display at the Step 1 of “Calibration Using a Calibration Weight”, and press the UNITS key and the current acceleration value will be displayed. ex. 9.7985 Step 2 Press the RE-ZERO and the digit that can be changed starts to blink. Change the value with following keys. RE-ZERO key To increment the blinking digit.
