What should I do if there is a negative number when the customer reports the Thickness Gauge measurement?

overview

When buying an instrument, in addition to looking at the parameters, brand, quality and price of the instrument, there is another problem that is easily overlooked, and that is after-sales service. If the after-sales service is not good, then you have to waste more time and energy to talk to the buyer, delay things, and mess up your mood. Is it not worth the candle?

Many people think that it is cheaper and more secure to buy directly from the manufacturer, but this is not the case. In terms of quantity, you and the manufacturer buy one or two large equipment or dozens of consumables/small equipment each time. And the price of dozens of equipment that Beichao and the manufacturer get every month, can it be the same?

We also have professional purchasing personnel to negotiate prices in real time, which cannot be done by individual purchases. Even if you can achieve a lower price than ours, can you see if the configuration can be the same? Is there a guarantee after sale?

Let’s talk about after-sales. We, NBCHAO, value the buyer’s experience, and we have a mature service tracking system in place for after-sales. If you talk to the manufacturer about after-sales service, if he argues with you, what can you do? He dares to lose you a customer, but he dare not lose us, because we can provide him with thousands of customers. do you understand?

For example, recently, a customer reported that the Thickness Gauge purchased from us from NBCHAO had measured negative numbers during use. We immediately asked the professional technical engineer in charge of the Thickness Gauge to contact the customer for professional guidance.

What should I do if there is a negative number when measuring the Thickness Gauge? Indicates that the instrument needs to be re-zeroed. You can contact the after-sales department to perform zero adjustment under the guidance. When zeroing, the uncoated substrate of the tested sample is used, so that the coating thickness of the tested sample is more accurate. If there is no uncoated substrate, you can use the zero adjustment board provided by us for zero adjustment, understand?
