Precautions during installation

1) Ensure to check power supply in the installation place! - This product is designed for AC 220V, 1 A, 1ph, 50/60 Hz. - If power voltage is wrong, over current may cause a damage of the machine. - If you have different power voltage, please contact us.

2) Check the status of power earthing. - Earthing work can prevent electrical shock.

3) Check input power cable. - If it is possible, use exclusive power cable for the machine. - If the thickness of power cable in the input part does not match the capacity, it can cause a fire owing to over load.

4) Install the machine on a flat place. - This product is precise machine. - Never install the product on a slope or uneven place.


- Please maintain level.

Power and earthing work

1) Power work - AC 220V, 1 A, 1ph, 50/60 Hz

2) Earthing work [Caution] - This product is designed for single phase 3 wire system based on standard of electric equipment. Be sure to connect the power cable to the plug with earthing. - If there is no earthing, it can damage electric and electronic parts owing to thunderbolt, etc. - In addition, it may cause electric shock.

How to use

Section - 5

① Tester must be installed on a place with no dust, humidity, or vibration.

② Install the machine a strong support, drill a hole on the prop on the lower part of the

SCREW about 90mm diameter and 160mm deep to allow lowering of the SCREW.

③ Install the machine a support, open the packing and then adjust horizontality.

To adjust horizontality, adjust horizontality to make test weight and test weight prop

is a straight line using horizontality adjusting screw.

④ Clean contacting surface on the lower part of ANVIL to sure that Anvil is free of filth

and/or oil.

⑤ Select a scale (Reference TableⅠ) suitable for a test sample, insert diamond cone or

steel ball indenter suitable for scale and then set test weight according to the scale by

turning test weight adjusting HANDLE.

⑥ Turn MAIN switch ON and check if the LAMP is ON.

If the Lamp is not ON, automatically move back to test position.

How to test (DTR‐200N)


⑦ Place a test sample on ANVIL and turn SCREW HANDLE clockwise to let short needle be

located at the middle of red point after the needle of the indicating GAUGE rotates 3 times.

⑧ Press START BUTTON to start operating. LAMP will be flickering and turned OFF.

At this point load will be applied and returned automatically. When a test is completed,

the LAMP will be ON.

⑨ When the needle of indicating GAUGE stops and LAMP is ON, a test is completed.

In case of diamond cone, read black number, and in case of steel ball indenter,

read red value as hardness value.

⑩ Turn SCREW HANDLE counterclockwise to remove test sample.



How to use

INDENTER

Test sample


① Locate a test sample on Anvil.

② Turn the handle clockwise to raise the Anvil.

③ When a test sample and indenter are met, the following screen will be displayed.

④ By turning the handle, the gauge number and ">>>>>" mark keeps progressing.

(Stage in which 10 kgf of preload is applied.)

Before test

- Check if the indenter and load is correct according to the scale.

- During inserting or taking out diamond indenter, be careful that the indenter does not bump into the Anvil on the lower part. Diamond indenter is relatively sensitive to impact.

- Check if the product is not shaking prior to any test.h l h l h l f f When a test sample is heavy, please pay attention to the sample for safety.

- Any person who conduct the test must wear gloves. If you touch Anvil with bare hand, it will get rusty easily and give small effect to hardness value.

After test

- During taking out an indenter after test, be careful that the indenter does not bump into the Anvil on the lower part.

- Replace the product cover after each test.

Weekly Maintenance

- Remove dust near and on the screw and clean the machine - Remove dust near and on the screw and clean the machine.

- Wipe each Anvil with oil to prevent rust.

Monthly Maintenance

R d t d th d l l b i t - Remove dust near and on the screw and apply new lubricant.

Yearly Maintenance

- To ensure the normal operation of the product, please conduct periodic calibration inspection every year.

FAQSection - 9

Error of hardness value.

Occurrence of an error of hardness value is caused by various reasonsOccurrence of an error of hardness value is caused by various reasons.Check for the error observing the following orders.

1. Damage of diamond indenter (in case of HRC measurement)

If k i d i i HRC l fi t f ll - If an error keeps occurring during measuring HRC scale, first of all, check for the damage on the diamond indenter.

- How to measure : 1) Check with tool microscope: 2) Scratch glass if there is any mark

- Measures : replace diamond indenter

2. Wear or bent of steel ball (in case of HRB measurement)

- If an error keeps occurring during measuring HRBW scale, it probably If an error keeps occurring during measuring HRBW scale, it probably because of bent or wear of steel ball.

- Measures : replace the ball

3. When you use a function of curved surface compensation for a flat test sample (DTR-300N model) for a flat test sample (DTR-300N model)

- In case of DTR-300N model, if there is big difference of value, check if there is any value for the function of curved surface compensation. (See 'How to use', page 8.)

- Measures : set both of D, R value to 0.


FAQSection - 9

Error of hardness value.

Occurrence of an error of hardness value is caused by various reasonsOccurrence of an error of hardness value is caused by various reasons.Check for the error observing the following orders.

4. Transport and re-installation of the product.

If h d th d t t di ti th l l t i - If you have moved the product at you discretion, the level or centering of a weight of for load pressurization is twisted causing an error.

- Measures : Open rear cover, adjust and centering of a weight for load pressurization to the centering of a support.

5. Upper part of screw cover is projected.

- You can remove screw cover according to test sample. Sometimes, screw cover has been raised to touch the Anvil Sometimes, screw cover has been raised to touch the Anvil causing big effect to a test.

- Measures : Turn screw cover to secure gap between Anvil and a test sample.

Maintain regular gapMaintain regular gap

Error during applying preload.

Check for errors observing the following orders.

1. In case of DTR-200N, when the small needle on the dial gauge does not move.

M Sh t OFF f b t 30 d d - Measures : Shut power OFF for about 30 seconds and turn back it ON.

2. In case of DTR-300N, when '>>>>>>' mark does not appear during applying preload. - Measures : 1) Shut power OFF for about 30 seconds and

turn back it ON.: 2) If it is not solved with the above measure, remove upper cover and then softly move the needle of digital gauge.

Remove upper front cover Softly press digital gauge rod


FAQSection - 9

Screw does not turn. (DTR-200N/300N)

In this case, Check for errors observing the following orders.

1. If there is no hole on the bottom of the product to allow the screw to be lowered, the end of the screw can contact the table.

- Measures : Lift up the product slightly and then raise the screw.
