Overview:
This application note details how to use a Fluke 6105 to verify a 3 phase Radian reference
standard, RD-3X, using the 8903 as an interface.
Procedure:
Currently, there is no way to automate the testing, so the test will need to be performed
manually.
Required Cables:
1. BNC-BNC
2. 5 Banana to Banana Plugs

- Page 1 Powermetrix Division Technology for Energy Corporation 10737 Lexington Drive Knoxville, TN 37932 (877) 966-5850 Verification Test for a RD-3X and an 8903 Overview: This application note details how to use a Fluke 6105 to verify a 3 phase Radian reference standard, RD-3X, using the 8903 as an interface.
- Page 2 3. 6-6MM to 6MM Current Plugs Connections: Before connecting the RD-3X, verify all connections on the Fluke and 8903 are correct and as pictured below. There should be three Fluke 6105’s, connected together via parallel port in the back of the unit. On the front side, all the Fluke should have their voltage and current connected to the front of the 8603.
- Page 3 This configuration should already be performed as this is the standard configuration for these units. Take the Radian and lay it face down to expose the connections on the back side as shown below. The connections are as follows 1. Red Circles: Phase Voltages 2.
- Page 4 Verify the commons are jumped together, and the correct phase voltages are connected to the correct locations.
- Page 5 Next, locate the 6mm locking current cables and connect them to the appropriate connections as shown below. Once done, the final connections on the 8603 should look like below. In essence, there are 3 6105s, connected as master-slave-slave, connected to the 8603, and the RD-33 connected to the same point.
- Page 7 Turn on the Fluke, and use the Select Menu from the keypad to highlight the Output menu with the blue border. Set the outputs to 120V and 0.5A. Use the dial to select a line, then use the Select Menu button to adjust down to the Waveform Menu portion of the screen. Set the correct range value, and then set the correct RMS value.
- Page 8 Once connected, turn the RD-33 on, and touch the “metrics” option.
- Page 9 Observe and verify the correct voltage and current values. Change values on the Fluke as desired.
- Page 10 Pulse Counting Test: Turn on the Fluke, and use the Select Menu from the keypad to highlight the Output menu with the blue border. Set the outputs to 120V and 0.5A. Use the dial to select a line, then use the Select Menu button to adjust down to the Waveform Menu portion of the screen.
- Page 11 Select Configure Meter Constants from the bottom blue menu. Set the meter base units to Real (Wh). Set the MUT (Meter Constant) and the Meter Constant Output to i/WH and the required value of the DUT. If the DUT’s i/Wh value can be edited, verify that the DUT and the Fluke are set the same to a value of choosing (100,000).
- Page 12 Take the BNC-BNC cable, and connect it from pulse output 1, on the radian, to channel 1 on the fluke, as shown below. On the Radian, select Configure device.
- Page 13 Select the tab labeled BNC output and verify that Port 1 is set to Total, and WH, as shown below. Next, select the tab labeled “BNC Const” and verify it is the same as the “i/WH” setting on the Fluke. Once the settings are correct, the DUT is wired and powered on, press the OPER button on the Fluke.
