It was the first purchase of Monotaro. It's a box and I found it soon! Cracked inside the display screen! I was surprised, it seems to be in transit if it is outside, but it is inside. . . . Please check before shipment. Claim correspondence was smooth!

I first used monotaro. It arrived and it was a box soon discovered! , How cracked the display screen! , In addition! Although it seems whether it is carrying on the outside, it seems that it is in transit, but if it cracks inward, I have doubts about honest quality control, it was disappointing, it is a surprise! . Refund exchange correspondence was smooth. Please check the appearance before shipment.

To count the number of durability tests of lighting equipment parts
From Japan
On 2017-03-17 16:48:03
It was shipped quickly after ordering. It is used for counting the number of blinking tests. It is useful to insert it on the bread board and use it. Although the counter itself is very compact, it requires an external battery and takes up space.

Purchase for machine maintenance
From Japan
On 2017-02-05 21:24:35
Omron of trust. I purchased it for machine maintenance. It is exchanged because the counter liquid crystal became hard to see on machines which had been about 15 years old. Although the model was changed, it got wider slightly but it is very appreciated to be a type that can replace the built-in battery.

I always use it because the battery was exhausted and it was a type that could not be replaced. The exchange was easy and it ended soon. Since the adapter was attached to the main body, it was not necessary

It was easy to install and good. Battery exchange may be troublesome by just saying battery type. There is no problem regarding use.

Measuring instrument panel surface mounting counter
From Japan
On 2015-03-07 13:26:32
I found out that I bought it this time, but it seems that I changed the model with the same model. Previous things used items of the same model with no reset button on the front. It was spot welding (?) So that the other person wrote the battery. The thing of this time has a reset button (I will not use it), I think that it is good for those who use it. Since the built-in battery for memory retention is also a battery box type (it seems * unconfirmed), it seems to be safe to replace immediately in case of emergency. The old type thing was an arrangement of two terminals on the back side, four terminals on the left and right, but this time the thing was changed to an array of four side by side. If you look at the included instruction sheet you will be able to connect and replace easily. It is a basic integration counter that counts the input (voltage / conduction), but the branch number is diverse. When ordering, let's specify the branch number that is suitable for the equipment.
