Our specialists can answer all your questions about different aspects of the world of weighing.
What do we mean when we talk about testing in the maintenance of a weighbridge?Action to perform a weight check with known masses or weight and from which no action is taken on the current adjustment without issuing a certificate.
What do we mean when we talk about adjustment in the maintenance of a weighbridge?Action to perform a weight adjustment with known masses or weight, from which the current adjustment is modified and from which no readings are taken to issue any type of certificate.
What do we mean when we talk about calibration in the maintenance of a weighbridge?Action to carry out, with masses, a data collection of readings at different points within the working range.
It is necessary to specify the values before and after adjustment. NO ADJUSTMENT IS NECESSARY.
An ISO type certificate or calibration letter is derived or, increasingly, certified by ENAC. This is in line with the client's quality procedure requirements.
This certificate contains a maximum number of error values stipulated by the regulations. This does not mean that they are not acceptable to the client, as the client ultimately decides on which errors are acceptable. These are specified in the client’s quality procedure.
What is primitive verification or EC?Action to be carried out by an approved body (e.g. Giropes), with a model approval (cells and display, with an assembly model) and with masses, taking data from readings at different points within the working range. Specify the values after adjustment.
AN ADJUSTMENT MUST BE MADE from which an EC type-examination certificate is derived. This is valid for 2 years (many companies do this every year to avoid mistakes and make sure they have everything correct. You can always be more restrictive than the norm).
In this certificate we have a maximum error value, which is half of that stipulated by the regulations. (0-500div to 0.5 E, 500-2000 to 1e and 2000-3000div to 1.5e). These values (data collection) are NOT delivered. If you want to collect data, it must be accompanied by an ISO or ENAC certificate.
* The primitive verification is the first verification of the machine or assembly. When there is a change of any element of the assembly (that changes its approval), the verification can be considered primitive. When it's no longer the first verification, it becomes periodic.
What is periodic verification?Action to be carried out by an official body for data collection, involving readings with masses at different points within the working range. Specify the values after adjustment. No adjustment will be necessary. A EC type certificate is derived from these.
This is valid for 2 years. (Some companies do this every year to avoid making mistakes and make sure they have everything right. You can always be more restrictive than the norm).
This certificate gives us maximum error values, which are stipulated by the regulations. (0-500div to 1e, 500-2000 to 2e and 2000-3000div to 3e). These values (data collection) are NOT delivered. If you want to collect data, it must be accompanied by an ISO or ENAC certificate.
What is the unitary EC?Action to perform EC or primitive verification by an approved body without a model approval (of approved equipment, but without an assembly model).
What do we mean by bottom of the scale?The full scale (FS) is the capacity of the scale or balance.
What do we mean by verification step?The verification scale interval (e) is the increment at which the scale is set.
What do we mean by minimum weight?The minimum weight in legal metrology is 20 increments from the working zero, i.e., the gross zero.
What is the difference between multi range and multi interval?If we take the example of a scale with a capacity of 6/15 kg:
When loaded they will behave in the same way, in 2g increments up to 6kg and in 5g increments up to 15kg.
Let’s analyse the following example for the multi interval device: I load in 2g increments (from 0 to 6kg) and unload again in 2g increments (from 6kg to 0kg). I therefore have only have 1 increment type around zero: 2g. The minimum weight is 20 x e = 20 x 2 = 40g.
On the other hand, in the multi range equivalent of this example we load in 2g increments (from 0 to 6kg) and unload in 5g increments (all unloading in 5g increments). So, I have 2 increment types: 2g and 5g. This means that, if I have two increments around zero, I will also have 2 minimum weights, one when loading (20 x 2 = 40g) and another when unloading (20 x 5 = 100g).
Evidently, the metrological label changes from one type to another.
I just installed my new weighing device and it doesn't weigh.See if the transport buffers are unlocked.
Then, if you still have no weight, make sure that your feet are positioned correctly and are not touching the platform.
Still not working?

The scale or display does not turn on.Make sure that the power cord or power supply is properly connected to the balance/display.
Check that there is power at the socket where you have connected the device.
My indicator/scale or the connected printer does not print.First check if there is paper in the printer and whether it is properly inserted. Check the steps explained in the manual that comes in the product box again, or download the manual from the download section.
Is there blank paper coming out? Check that the thermal side of the paper is properly positioned (if you are not sure, turn the paper over).
Still not printing? Make sure the paper is thermal by rubbing it with your fingernail.
The weight is fluctuating.Step 1. Make sure all four feet are touching the ground.
Step 2. Check that the battery is charged.
Step 3. Check the cell cable connections.
Step 4. Check that the cable is in good condition.
Won’t communicate in RS232?Make sure that the transmission speed and the type of parity are the same between the devices.
Is the GI650i indicator USB input for keyboard and cursor?No, the device's USB is configured for use with a keyboard and for data export and import.
Does the GI650i indicator database support the creation of fully customised tables?No, you have to use the conformed CSV format.
Does the Gi650 have an option for digital cells, or just analogue?It has a version for analog load cells and another for digital load cells.
Can the GI650 indicator be connected to an ERP?Not in principle, but it can be weighed under study.
Can I download the weights (GI6xx indicators)?Yes, provided that you choose the product with (optional) USB when ordering.
Can I get the signal from the platform directly? Can I have relays that activate? Can I have the signal in mA?The platform itself must be supplied with a very well regulated voltage to obtain a differential mV voltage (from 0 to 10 mV in most cases) that you have to filter, amplify, convert to weight, etc. All this is done using the indicator.
Once you have the weight on the indicator you can send it by RS-232 that it takes from series, or through RS-485 or Ethernet using the optional boards that it has. This weight is sent with the selected communication protocol for each port. If necessary, for a small fee, customised protocols can be added.
You can also convert the weight signal to analogue again, but this requires much more “power”. This is the case of the optional analogue output, which allows you to have a signal proportional to the weight, either voltage from 0 to 10V or current from 4 to 20mA.
Another option is to add a relay board. This allows, using the "limits" mode, a value to be assigned to each relay, so that they are activated when they reach the designated value. Or, by means of the "Z rel" option where there is a relay (RL1) that is only active if the weight is exactly at the set value and another relay (RL2) that is active until the programmed weight is reached.
Do I have to be next to the indicator to use the GIAPP?No. With the WiFi option, the indicator creates its own network to which an Android device can connect. The average range is approximately 75 metres, depending on the structure of the environment where it is used (walls, metal structures, etc.).
You also have the option of connecting the indicator to the company's WiFi, its range would depend on the company's own WiFi, and could exceed 75 metres from indicator to Android device.
Can I use the GIAPP without the WiFi module on my indicator?Yes, if this one has the Ethernet module. The Ethernet module can be used to connect the indicator to the system's WiFi network, and the indicator can be displayed and controlled via the GIAPP.
