is the meter need Calibrated ?

FROM HM DIGITAL: The COM-100 has been factory calibrated. It will retain it's calibration for 2-3 years, and the factory calibration is suitable for most applications. However, for all scientific testing, a meter should be calibrated as close as possible to what will be tested, or in the middle of range that will be tested. Therefore, you may wish to recalibrate, but it is factory calibrated and ready for use right out of the box.

You need a device such as the RadioShack Digital SPL meter.The Emm-6 through software (such as the free Room EQ Wizard) can measure SPL but even then you still need a dedicated SPL meter to calibrate the software

No, the meter does everything as expected. One thing is, you should make sure that the probes are clean and dry before testing each time you take a reading.Bob

No special calibration is needed. As far as what tools to use, there should be instructions with your kit about the installation process.

I found nothing in the instructions on how to calibrate. We just installed ours and so far it's accurate. Time will tell.

Should have a small data info sheet in the bottom of the box it comes in. The connector that has two wires(I used a nine volt battery with a switch), red & black are for display power. The other wires are for voltage sense & amperage (milli-volt) from shunt. Yes, a shunt is required. This is a good meter, just not enough information to support it's installation & calibration. Two adjustments (apex) on the P.C. board are for the calibration of the volt meter & amperage read-outs.

No, you do not have to calibrate this scale. It work great just out of the box. I highly recommend it!

No. The meter must be powered by a voltage between 4.5 - 30 VDC. It will happily measure the 52 VDC source, but you will need either a voltage regulator or a separate power source (like a battery pack) to power the meter. If you use a battery pack to power it, you will need to connect the (-) terminal of the battery to the (-) connection of the voltage source you are measuring so that they will have a common ground.

I have never tried calibrating it with a thermometer close by but it seems to work well cycling my electric heaters on the ceiling. I have two of them and they they both work fine. Would buy them again.

Hi Zitch I just look up the operating instructions on line and it does not indicate that you can calibrate this gauge. I have checked mine against a few manual gauges and it was very accurate. Hope this helps. Dave.

I found no calibration feature. You can contact the manufacturer and they will answer your question further.

A calibration is required each time when it is first turned on. Very easy. Place a testing tube of plain pool water in the device and start.

The only answer to your question that I have is that I didn't have to calibrate mine, and it seems to work correctly. This is not a hi-tech compass. It's pretty cheap overall. But if you can't afford a good one, it works in a pinch. It sticks to your window wherever it is convenient for you.

If by "calibrate" you mean manually set the thermometer to a specific temperature, then the answer is "no". On the other hand, if you mean by "calibrate" to check out against a preset temperature, then "yes" you could do this..e.g., immersing the probe in an ice bath.

In order to calibrATE you do need the packets and thew ionized water. Unless you can get a lab to check it against their equipment

I bought those too, the readings with the no-calibration strips still came out as 0.1's almost all the time with occasional 0.2's just like the first set of calibrated strips that I had bought with the meter originally. I'm an engineer and don't know exactly how they do it, but nanoscale manufacturing these days is doing amazing things so maybe the calibration sample is on the strip sub-microscopically and we simply can't see it. Just follow the instructions and be happy.

I don't think it is needed. Just do a check on bottled purchased water. Every so often recheck and see if reading are same if yes no calibration required.
