Frequently Asked Questions - TB 74 Testboy

How to use the Testboy TB 74?

Remove the cover of the tester and press the button to turn on the device. Hold the probe on the surface to be measured and read the result on the LEDs. Replace the cover after use.

What do the LED colors mean?

The LEDs indicate the coating thickness: green = 0-150 μm, green/yellow = 150-250 μm, yellow = 250-350 μm, yellow/red = 350-400 μm, red > 400 μm.

How to replace the batteries?

Remove the battery compartment cover by pushing the clip upwards. Insert a 12 V type V23 battery observing polarity, then close the cover.

What is the measuring range of the TB 74?

The measuring range is 0 to 400 μm (micrometers).

Does the device have automatic shut-off?

Yes, the Testboy TB 74 is equipped with an automatic shut-off system to save batteries.

How to clean the device?

Clean the device with a dry cloth. Do not use aggressive products. Remove the batteries if you do not use it for an extended period.

Operations

Thank you for choosing the Testboy ^® TB 74.

The test probe can be used for making digital measurements to determine the thickness of layers on magnetic metals. It is designed for use in professional workshops and service departments. Three LEDs are used to indicate the thickness of the layers within different ranges.

Automatic power-off

The Testboy TB 74 features an automatic shut-off feature.

Determining the layer thickness

Remove the tester's lid and press the button to turn it on. Hold the test probe on the surface to be measured while simultaneously reading the result on the LEDs.

Displayed result Button Slide off cover

Display

The display consists of three LEDs that indicate the layer thickness range.

Red >400 μm

Yellow / red 350 - 400 μm

Yellow 250 - 350 μm

Green / yellow 150 - 250 μm

Green 0 - 150 μm

The device is pre-set to these ranges and does not need to be calibrated.
