PosiTector PC Powder Checker Q & A

Q. Is there only one model?

A. Yes. The PosiTector PC Powder Checker measures from 20 to 110 microns (0.8 to 4.3 mils) and is suitable for a majority of powder applications.

Q. Why measure uncured powder?

A. Coatings must be applied within certain minimum and maximum dry film thickness specifications. But waiting to measure coating thickness after curing can result in product waste and production delays. Accurate measurement at the time of application:
  • Eliminates over usage
  • Improves quality
  • Controls set-up
  • Reduces waste
  • Saves money!

Q. Are there simpler, cheaper ways to measure powder height?

A. Handy, inexpensive powder combs are available. However, coating powders diminish in thickness during the curing process, so measuring powder height in the pre-cured, pre-gelled state requires a correlation factor be calculated and applied to every measurement for every powder. Marks will be made in the powder that may not be covered when the powder flows in the cure process.

Q. Can I measure cured powder thickness with the PosiTector PC post cure?

A.No. The PosiTector PC only predicts cured thickness by measuring applied, uncured powder. Use the PosiTector 6000 to measure the post-cured powder coating thickness.

Q. Does the PosiTector PC imprint or dimple the powder?

A. No contact is made during measurement and there are no cables to accidentally brush and disturb the powder.

Q. Does it comply with any industry standards documents?

A. The PosiTector PC complies with ASTM D7378, “Standard Practice for Measurement of Thickness of Applied Coating Powders to Predict Cured Thickness”.

Q. How do you operate the PosiTector PC?

A. Turn both the base unit and probe on, press the probe button and hold it 18 mm (0.75”) from the part for 2 to 5 seconds. The predicted cured thickness result immediately appears on both the probe and base unit displays.

Q. How far away can the wireless probe be from the base unit to measure remotely?

A. The wireless probe has a range of 10m (30 ft.). The base unit can attach to your belt, remain in the carry case, or conveniently attach magnetically to a nearby steel structure.

Q. How do I know that the base unit has received my readings?

A. The instrument will not operate unless the probe and base unit are communicating with each other. Set-up is immediate and automatic. Each measurement result is displayed on both the probe and base unit. Both units beep and flash simultaneously. Both will power-down automatically after a period of no activity.

Q. Can I connect other probes?

A. No. The base unit can only communicate with ONE probe using a permanent Bluetooth connection. If either the probe or the base unit should need repair, both must be returned for service.

Q. Can I pair the probe with another Bluetooth device?

A. No. The data transmitted between the probe and the base unit is secure . Neither the probe nor base unit can be paired with another Bluetooth device. The probe will only communicate with the base unit.

Q. Can I download readings stored in memory from the gage to a PC using Bluetooth?

A. No. While the probe and base unit communicate via Bluetooth, readings stored in the base unit’s memory are accessed using the supplied USB cable.

Q. What is USB Mass Storage?

A. USB Mass storage is an internal memory storage file system in the base unit that stores 1,000 readings in up to 100 batches. Stored readings are accessed using a common USB cable in a manner similar to flash (thumb) drives, cameras or digital audio players. Navigate to readings and reports using your computer’s browser. Simple. Most personal computers support USB.

Q. What are the benefits of Mass Storage?

A. There is no need to install software onto your computer. Modern operating systems can read directly from the PosiTector PC without installing device drivers. Connect the PosiTector PC to a USB port and have immediate access to your measurement data and charts. One-click printing of formatted reports, or cut-and-paste into your application.

Q. Do I have to hold the probe steady during measurement?

A. No. In fact, the instrument performs best when there is slight movement. It was designed to measure moving parts on hooks.

Q. When measuring, the result on the probe and base unit occasionally changes by several digits after I remove my finger from the probe. Is this OK?

A. Yes, this is normal operation. There is a queue of samples that are still being processed after the button is released.

Q. What types of batteries are used?

A. The wireless probe uses 3 “AA” alkaline batteries. The base unit uses 3 “AAA” alkaline batteries. Battery icons display a full bar with fresh alkaline batteries installed. As the batteries weaken, the bar will be reduced. When the battery icon is low, the instrument can still be used, but the batteries should be changed at the earliest opportunity.

Q. What are the optional accessories?

A. The PosiTector PC has 2 available options.

  • IR Printer receives data via wireless infrared
  • Replacement probe screens (Qty 2) to protect the probe transducer
