Users Manual

1 .Rotate to right to loosen the locking screw of the caliper and release the lock of the caliper, then hand- pushed roller caliper can be moved 2 .Turn on to check if the caliper display and keys work. 3 .Clean the measuring surfaces of the measuring tool. Close the measuring claw with appropriate force, shortly-press /0 to turn on and set a.Press the switch or pull the caliper frame to light up the display. b.According to the measurement requirements, press the Metric/inch button to select the measurement unit. c.Move the caliper frame so that the measuring surfaces of the two calipers are in close contact with the surfaces of the measured object, and then read the value shows on screen. Normal mode Turn on the power supply, the display shows the position of the ruler frame before turning off the power supply, and the zero position (origin) of the caliper is the last set zero position (origin) before turning off the power supply. When using the absolute measurement mode, there is no need to adjust the origin position. When using the relative measurement mode, Press INC to adjust the zero position (non origin) according to the demand. Power saving mode (shutdown time is more than 8 hours): turn on the power supply, and the absolute measurement zero position (origin) of the caliper is the position of the caliper frame when starting up. After the measuring surface needs to be cleaned, move the ruler frame to close the measuring surface, and long press the /0key for five seconds to reset the zero position (origin) of the absolute measurement mode. d.Switching between absolute measurement and relative measurement Product features 1.Set zero at any position. 2.The measurement unit can be set to mm/in/F. 3.Can maintain the consistency of the origin. 4.Whenever it is turned on, the LCD will display the current ruler frame position at any time 5.The absolute origin is adopted, and there is no need to adjust the zero position repeatedly. 6.Minute automatic screen shutdown, 8-hour automatic power failure, low power consumption design 7.No response speed limit, no error due to average speed change Product Figure and Buttons Parameter 0-150mm(0-6")/0-200mm(0-8")/0-300mm(0-12") 0.01 mm/0.0005" /1/128" CR2032 lithium battery 0-80% 0-40°C (32-104°F) Instruction manual IP67 DIGITAL CALIPER 4.mm/in/F button: Press this button can change measuring standard. 5.Locking screw: Left twist for fixing caliper position, right twist for unlock. 6.Battery cover: replace battery. 7.Thumb roller:used to push measurement. 8.Scale 9.Beam 10.Depth measurement rod: measuring depth. 11.lnternal jaws: measuring Internal dimension. 12.Step measurement: measuring step dimension. 1 14.Bluetooth 3.External jaw: measuring external dimension. 2.LCD screen: display measurement value. 1. /0 button: Press and release Poweron/ o ff , S ystem will work under absolute measuring mode when power on.If "SET"shows on the screen, pls long press this button to set ZERO. 3.INC button: Press and release the button:at any position. LCD will display"0.00"and "INC",the caliper is ready for relative measurement. Press and can turn back the absolute measurement. This time the symbol "INC" disappear. Long press the button:LCD will` display"0.00",The origin is set at this position. Relative measurement: briefly press the INC button, the Inc indicator appears in the left corner of the LCD display, and the caliper enters the Inc memory measurement. At the same time, clear to zero, and start counting from the position of the caliper frame to zero when pressing the INC key. Absolute measurement: press the INC button in the relative measurement mode, the Inc indicator will disappear and return to the absolute mode, and the counting will start from the zero position (origin) set by the startup. a) Remove and immediately recyce or dispose of used batteres according to local regulations and keep away from children. Do NOT dispose of batteries in household trash or incinerate. b) Even used batteries may cause severe njury or death. c) Calla local poison control center for treatment information. d) Battery type: CR2032 e) Nominal battery voltage: 3V f) Non-rechargeable batteres are not to be recharged. g) Do not force discharge, recharge, disassemble, heat above (manufacturer's specified temperature rating)or incinerate.Doing so may result n njury due to venting,leakage or explosion resulting in chemical burns. h) Ensure the batteries areinstalled correctly according to polarity (+ and-). i) Do not mix old and new batteries, different brands or types of batteries, such as alkaline, carbon-zinc, or rechargeable batteries. j) Remove and immediately recycle or dispose of batteries from equipment not used for an extended period of time according to local regulations. k) Always completely secure the battery compartment. If the battery compartment does not close securely, stop using the product, remove the batteries,and keep them away from children.
