Q1.
How the impact speed will affect to the measured data?
A1.
The impact speed of the hammer can be calculated by the accelerometer installed on the hammer, and the measured data is automatically corrected. If the impact speed is appropriate, CTS beeps 1 time. When the impact speed is too fast, CTS beeps 3 times and if you do not hear any beep, you need to hit faster.
Q2.
How deep CTS can measure?
A2.
Measured data of CTS reflects approximately 50mm from the concrete surface. The Figure shown in below is a measurement result of testing a concrete cube that contains 3 pieces of polystyrene foams at a depth of 15mm, 25mm and 35mm from the surface. You can see the polystyrene is still affect to the measured data even 35mm.
Q3.
How the depth of concrete shall affect to the measurement?
A3.
CTS is not applicable for thin concrete plate (less than 100mm) because the concrete may be bent by the impact. Your target concrete should be more than 100mm.
Q4.
Can CTS measure the strength of concrete covered by layer (coating materials)?
A4.
No. You need to hit the concrete body directly.
Q5.
I want to perform a calibration test on the device.
A5.
Please contact the store where you purchased the product. The manufacturer recommends a calibration test once a year or once every 50,000 blows.
Q6.
When I try to save (copy) the measured data to my PC, an error message appears and I cannot save the data.
A6.
The internal battery of the main unit may be dead. Please contact the store where you purchased the product.
I would like to know the applicable bolt and nut sizes.
The BOLT-Tester comes with three hammer sizes: small, standard, and large, with small being M8 to M12, standard being M12 to M20, and large being M20 to M24. These are guidelines for general post-installed anchor bolts, and the applicable size will vary depending on whether you are testing for nut loosening or the type and length of the bolt.
Where can I buy the products? Do you offer leasing and rental?
