Verification Box Assembly
This Verification Box provides more accurate voltages than a direct connection to the 5520A. The 5520A uses a divider with a 50 Ω output impedance when sourcing <330 mV. Due to variations in the Logger input impedance, the actual applied voltage is less than the programmed voltage. Using an external divider where the parallel resistance is ~30 Ω allows calculation of the applied voltage with confidence that the Logger input loading will not significantly impact the applied voltage.
Fluke recommends using a verification box that has a divider with 30 Ω across the Logger input and 10 k Ω in

Basic Instrument Setup for all Verifications
The Fluke173x_354x-ExcelTool_Vxxx (ExcelTool) has built-in procedures to verify and adjust the Logger.
The Verification uses an external divider. This divider, (see Verification Box Assembly) provides more accurate voltages than a direct connection to the 5520A. The 5520A uses a divider with a 50 Ω output impedance when sourcing <330 mV. Due to variations in the Logger input impedance, the actual applied voltage is less than the programmed voltage. Using an external divider where the parallel resistance is
~30 Ω allows calculation of the applied voltage with confidence that the Logger input loading will not significantly impact the applied voltage.
The ExcelTool calculates the voltage that should be applied based on the values entered in the setup screen.
1.
Apply power to the Logger using the power supply and line cord.
2.
Turn on the Logger.
3.
Connect the Logger USB to the PC and start a communication program. See USB Communication.
4.

Fluke recommends using a divider with 30 Ω across the Logger input and 10 k Ω in series with high side of the input:
• Fluke PN 2114858 (10 k Ω )
• Fluke PN 1757740 (30 Ω
) – see Table 6 for the recommended assembly of this divider. Best practice is to
measure the resistor values at time of use.
Caution
Be careful when you set the calibrator output voltages. High voltages applied to the current input will damage the Logger.

Optional Verification for Flexi or Clamp (Combined Logger and Probe Specifications)
This feature of the spreadsheet checks the Logger combined with current probes. These tests use the 552x and the 5500 Coil, or the 52120A Coil as an option. The Test Uncertainty Ratios (TUR) is typically <2:1. This system can only source 1000 A, consequently, this test will not be made at full-scale of the Flexi probes.
To connect the customer current probes to the Logger:
1.
Connect the VL1730 "N" lead to the calibrator NORMAL LO.
2.
Connect the calibrator NORMAL V output to the VL1730 L1+L2+L3 leads.
3.
Connect the calibrator AUX jacks:
AUX LO. For a i40S-EL clamp, connect a 5-turn coil to the calibrator. Connect the red jack to either the
AUX jack when <3 A is requested or the 20 A jack when >3 A is requested.
• For the 52120A Coil verification (see Table 14) connect calibrator AUX HI and LO to the 52120A
INPUT HI and LO.
4.
Connect the current probes under test:
• For the 5500 Coil verification through the 5500 Coil with arrows pointing up for the correct phase match.
• Pass the Flexi, or clamp under test through a single loop, or 3 KA coil, or 6 KA coil, with arrows pointing up for the correct phase match as indicated in the table.
5.
The spreadsheet Verification tab has an Attached Sensor drop-down list box to select the probe that is connected.

Calibration Adjust Procedure
This procedure adjusts the Logger accuracy at ambient temperature 23 ° C ± 2 K (intrinsic error).
The required equipment and cables for calibrating the Product are listed in Table 3. See USB
Communication for instructions on how to set up the PC.
Warning
To avoid electrical shock, personal injury, or fire:
• Do not perform the calibration procedures or calibration verification tests described in this manual unless you are qualified to do so.
• Repairs or servicing should be performed only by qualified personnel.
The spreadsheet contains an automated adjust in the Calibration & Verification worksheet. When used, it provides connection instructions, can control the calibrator to apply the required voltage, and then will calculate and store the new calibration factors.
When this worksheet is active, the selection box should pop up. If not, click the Start button on the upper right of the worksheet.
In the Setup tab, only the calibrator control needs to be set (the Voltage divider is not used in the 173x
Adjust).
Select the Calibration tab of the 173x Calibration & Verification pop-up. Choose Voltage, AUX, or Current calibration and check the boxes to select items for adjustment.
1.
When selection is complete, click Start.
2.
Follow the instructions provided in the automated procedure.
Note
The calibration adjust of the 3540 FC is done on the phase currents
L1/A, L2/B, L3/C. Adjustment of the plugged neutral current is not supported.
When the 173x Calibration & Verification popup box shows again, the calibration factors have been calculated and stored in the Logger.
This concludes the calibration.
