MANUAL PCE-TG

∅

Overview

PCE-TG is a miniaturized ultrasonic thickness gauge which can measure thickness.

Keypad

ON - Turn on the gauge

OFF - Turn off the gauge

- Menu key. Circularly press to enter into different mode

- regulate the twinkling number (up)

- regulate the twinkling number (down)

- move the twinkling number on rightward

LCD display

THK - thickness measurement

CAL - calibration function

VEL - velocity setting

m/s - unit of velocity of sound

mm - unit of thickness

Calibration

9 Press menu key until CAL 0.0 displays on LCD.

9 Take the probe to measure the block of 3.0mm attached on the panel of gauge.

9 After 3.0mm displays, the gauge will automatically finish calibration and the display will come

back into the mode of measurement.

1. Change velocity

9 Press menu key consecutively until VEL and current velocity value displays on LCD.

9 Press key Δ or ∇ to change the value of velocity to be wanted.

Note: Press and hold

Measuring velocity

9 Press key consecutively until both THK and VEL display on LCD. And also last stored

thickness value will display.

9 Press Δ or ∇ to change the number to be the value of measured material.

9 Take measurement on the material and after new velocity of this material displays, the gauge

will automatically save this velocity and go into the mode of measurement.

Δ

or ∇ to let changing number go fast.
