Specification: Condition: 100% Brand New Item Type: Pocket Scale Style: 20/0.001g, 30/0.001g, 50/0.001g(Optional) Material: Plastic Color: As shown in the picture Size: Approx.144x84.5x51mm / 5.7x3.3x2.0in Weight: Approx.314g~344g/11.1oz~12.1oz Battery: 2 x AAA batteries(Not included) Starting Value: 0.003g Repeatability: 0.002g Low Power Alarm: "LO" Scale Plate Size: Diameter: Approx.32mm / 1.26in (with stainless steel weighing plate) Function Keys and Instructions: 1.ON/OFF(switch machine key) Load 2 AAA batteries(not included) in the direction specified in the battery box and close the battery door. Put the scale body on a stable desktop, keep the horizontal bubble in the center of the black circle, turn off the machine and press this key to display "88888" and return to zero to start up. At this time, the loaded items can be weighed in the scale plate, and press this key to shut down when weighing. Weigh the environment. If there is wind, please put down the windshield and measure. 2.UNIT Press this key to select different weighing units: G,OZ,GN,CT,T,OZT, Long press the unit conversion key for 4 seconds will light up all units, OZ units will flicker, press the peel key PCS can choose to hide or display, press the unit conversion key to shift another unit, (this function for customers to choose practical units to retain the choice). Exit long press 4 seconds to return to normal mode. G units cannot be concealed. 3.TARE Press this key to force the reset to zero when starting up the weighing state. 4. PCS (counting function) Boot after zero, points to a 25 or 50,75,100 arbitrary sample value, put it on the scale weighing, the long press count LCD displays a default values (such as P 25) count release button, and press unit conversion option (25,50.75, 100) just points model numerical value, of the press button to confirm again, the LCD shows the number of PCS + samples values values (50), the can scale load need to count the items at the moment. The Calibration Function: Long press the startup button for 4 seconds, and then -0- (zero point) will be displayed. Wait for 1 second, and then the weight value to be calibrated will be displayed. Thus, the maximum weight of the scale is 30G (flashing 30.000). (this product is random distribution of 20 grams, press unit count down to 20.000, load calibration completed after 20 g weight shows PASS) calibration weight value flashing, press unit conversion, press count impairment, according to the size of 10 g and subtract can choose appropriate needs calibration weight value of 10 g - 30 g, shut down after the memory of the last set calibration value. Automatic Shutdown Time Setting: Long press the ON/OFF button for 4 seconds under shutdown state to display 88888 and do not let go until the display f1-1 press the UNIT key to select 0-5 values corresponding to 0= no shutdown state 1-5 respectively indicates that 1 to 5 under no operation state is divided into automatic shutdown time. According to their needs to choose the appropriate shutdown time to save battery life. After the selection, press the startup key to return to zero to weigh.
