Description
Overview
GAOTek Coating Thickness Gauge with 0 Span Calibration (Light Weight) is designed to magnetic and nonmagnetic materials in high resolution and wide measuring range of 1 μm to 1250 μm. It uses magnetic induction method and eddy current method to measure thickness of magnetic coating on non-magnetic base. This light weight instrument is suitable for use in harsh conditions. This instrument provides under voltage and error indicator, automatic shutdown, zero calibration, span calibration and prompt beep operation function. This rugged and versatile device can be used in the field of chemical industry, commodity inspection, manufacturing, metal processing industry and other testing.

Operation Guide
- Power-on and Warm-up
Keystroke once; wait until 
is displayed on the LCD. Now the gauge is ready for measurements.
- Zeroing
Keystroke twice; when 
is displayed, place flat on surface; hold steady.
After measurement is obtained, 
is shown and gauge beeps. Then lift the gauge.
3. Two-Point User Calibration
Keystroke three times; gauge enters into the mode of two-point user calibration.
When 
is shown on the LCD, please conduct a measurement on the base. When 
is shown on the LCD, place Shim S1 on the base and conduct a measurement on Shim S1. When 
is shown on the LCD, place Shim S2 on the base and conduct a measurement on Shim S2. When
is displayed, it is ready for use.
4. Unit Change
Keystroke four times; convert from ums to mils or vice versa.
5. Reset
Keystroke five times; gauge resets.
Measurement Range: 0 um–1250 um or 0 mil–50 mil
Accuracy: ± [(1%~3%) H+1 um] Note: H is thickness reading
The device powers down after 60 seconds of no activity.
