Proster 0-225°Digital Inclinometer Protractor Angle Finder

Description: It is a digital angle measuring device whose read is easier and exact than other scale indicated angle level.It is mainly intended for applications which involve lineation for woodworkers, measure and definition of the exact angles such as trays, sloping roofs and handrails.It also can be used as spirit level to quickly measure the horizontal and vertical angle. Feature: Backlight design: keep its normal use on dark light.Data holding function: Help the use on dark light.Mechanical lock (Lock knob): Keep the angle invariable in the process of line or measure the angle.The value of the angle increases or decreases in the step of 0.1° as you open or close the angle.ON/OFF LED Lighted displayON/OFF Button Specification: Length: 400mmIncrease/decrease angle: 0.1°Measuring range: 0-225°Measuring precision: ±0.5°Working temperature: -10°C~+50°CBattery: 9V 6F22   Operating Procedure: 1. MEASURE ANGLES FUNCTION1) Switch on SK99G.2) Unfold the arm of ST99G, the opening angle increases or decreases on LCD display.3) Adopt the comparative method to measure the angle or set the lineation angle.4) You can fasten the Lock Button to keep the angle invariable when drawing the angle line.5) Open the backlight when the beam is dark.2. Spirit level Function: Quickly measure the horizontal and vertical degree.   CAUTION: 1. Do not move the screws and components at random.2. Please handle your angle meter with care, use even strength to rotate the Rotate Arm, and do not use too much strength.3. Do not keep the backlight open for a long time.4. When the low power Alarm icon appears on the display, please change the batteries   Package: 1*Digital Angle Finder1*Angle Finder Case1*Portable bag1*user manual
