PMV INVESTOR Functions The PMV INVESTOR uses up to four different measurements to determine if a coin or bar is consistent with genuine precious metals. The four measurements are: 1. Basic Verification Mode: The PMV INVESTOR Wands measure the sample’s resistivity just under the surface of the metal.
How to get the most out of your PMV INVESTOR The PMV INVESTOR is used to test the resistivity and density of precious metal coins and bars. A genuine sample should pass both resistivity and density testing. It’s important to use the right settings and sensors to make sure your PMV INVESTOR is providing the best results.
Power On and Calibrate Power on your PMV INVESTOR by pressing the POWER button. The device will display the serial number, firmware version, FPGA version, and database version. The device self-calibrates during the power on stage. While the device is powering on, ensure there are no samples on the device and that the arm is in the upright and resting position.
Setup You may change some settings in the SETUP screen. To access the SETUP screen, press the RIGHT button on the READY screen. Use the UP and DOWN buttons to select the category, and use the RIGHT and LEFT buttons to change the selection within a category.
Metal Selection Prior to taking a measurement, you must select the appropriate metal or alloy from the metal selection database. Choose the metal you expect the sample to be. Press the METAL button to open the selection menu. Use the LEFT and RIGHT buttons to navigate between metal categories, and use the UP and DOWN buttons to select a specific metal within a category.
Weight Entry Press the WEIGHT button to enter the weight of a sample. You can either select from the options listed in the English Units (Ozt) and Metric Units (grams) categories, or you can manually enter a weight on your own. Use the LEFT and RIGHT buttons to navigate between categories, and use the UP and DOWN buttons to select options within a category.

Manual Weight Entry To manually enter weight, use the UP and DOWN buttons to select the type of weight you want to enter. Press the ENTER button to change the indicated weight. Use the NUMBER buttons to enter the desired weight. Press the WEIGHT button when finished to save the entry.
Measurement Screen The MEASUREMENT screen will display when taking a reading. Below is a basic explanation of each part of the screen. The screen will not display the diameter, thickness, or weight if weight mode is turned off. When using a Wand attachment, only the Basic Verification Mode bar will display.
Resistivity Testing The INVESTOR’s onboard sensor and Wands test the characteristic resistivity of precious metal coins and bars. Each precious metal alloy has an expected resistivity value; the PMV’s sensors test the sample’s resistivity and compare it to the known resistivity of the selected alloy.

Dimension Verification To verify the dimensions of a sample, the correct metal must be selected and the correct weight must be entered. To verify the dimensions of a sample, press the MEASURE button while the device is reading the sample with the onboard sensor. The INVESTOR has two dimension verification modes.

Numerical Dimension Verification To verify the dimensions of a sample, the correct metal must be selected and the correct weight must be entered and the sample must be tested using the onboard sensor. To verify the dimensions of a sample, press the MEASURE button while the device’s onboard sensor is reading the sample.

Visual Dimension Verification Select the shape of the sample using the UP and DOWN buttons. Once the DIMENSION screen appears, you may move the sample away from the sensor. For round samples: align the right edge of the sample to the vertical solid black line on the right-hand edge of the •...
Wand Use Wands are optional attachments for the PMV INVESTOR. To use a Wand attachment, plug the Wand into the Wand Connector on the right-hand side of the device. When you plug in the Wand, the device will self calibrate. Ensure the head of the Wand is at least one inch away from any metal during this calibration process.
PC Interface The PMV INVESTOR is capable of using a Windows PC (Windows 7, 8, 10, and 11) as an interface for the device. You must first install the PC Interface program by downloading it from our website (www.sigmametalytics.com/investor-pc) and following the included download and installation instructions.
Testing Best Practices Below are the best practices for testing with a PMV: Determine the expected alloy of the sample before Determine a sample’s expected alloy before testing and select testing. that alloy from the metals menu. The PMV is not designed to “find”...

Testing Best Practices The PMV is a powerful tool for testing the resistivity and density whatever non-destructive testing you can. of samples. However, always perform whatever additional, non- destructive testing you can, such as examining the sample’s markings and designs and checking the sample’s provenance. More non-destructive testing is always good and a genuine piece should pass every test.
Common Questions Our “Pure Silver” range is calibrated to put .9999 silver in the Why does my silver read in the yellow? green and .999 silver in the yellow on the right. We do this because we so frequently see .999 silver counterfeited that we want all users to be cautious of .999 silver samples and to check the other aspects (markings, weight, and size) of the sample prior to making any judgment.

Common Questions The device needs to be actively measuring the sample when Why doesn’t the dimension screen come up? you press the MEASURE button to bring up the dimensions verification screen. If the device is not actively reading a sample, pressing MEASURE will not bring up the dimensions screen.
