LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The
warranty period is two years and begins on the date of shipment. Parts, product repairs, and services are warranted for 90
days. This warranty extends only to the original buyer or end-user customer of a Fluke authorized reseller, and does not
apply to fuses, disposable batteries, or to any product which, in Fluke's opinion, has been misused, altered, neglected,
contaminated, or damaged by accident or abnormal conditions of operation or handling. Fluke warrants that software will
operate substantially in accordance with its functional specifications for 90 days and that it has been properly recorded on
non-defective media. Fluke does not warrant that software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no
authority to extend a greater or different warranty on behalf of Fluke. Warranty support is available only if product is
purchased through a Fluke authorized sales outlet or Buyer has paid the applicable international price. Fluke reserves the
right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted
for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or
replacement of a defective product which is returned to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information,
then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB
Destination). Fluke assumes no risk for damage in transit. Following warranty repair, the product will be returned to Buyer,
transportation prepaid (FOB Destination). If Fluke determines that failure was caused by neglect, misuse, contamination,
alteration, accident, or abnormal condition of operation or handling, including overvoltage failures caused by use outside
the product’s specified rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of repair
costs and obtain authorization before commencing the work. Following repair, the product will be returned to the Buyer
transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY
CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of
incidental or consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any
provision of this Warranty is held invalid or unenforceable by a court or other decision-maker of competent jurisdiction, such
holding will not affect the validity or enforceability of any other provision..

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 kΩ in
series with high side of the input. See Table 6 for instructions on how to make the verification box.

System Requirements
The system requirements for this verification procedure are:
• WinXP 32-bit, Windows 7 32/64-bit, Windows 8 32/64-bit, Windows 10 32/64-bit
• Monitor, 1280 x 1024 (@4:3) or 1440 x 900 (@16:10), wide-screen (16:10) at higher resolution recommended
• USB 2.0 port
• RS232 port or USB-to-RS232 converter to control the calibrator (optional)
• Microsoft Excel 2010 32-bit software or higher (versions below 2010 not tested)
• Fluke Energy Analyze software
USB Communication
Some of the range changes in the verification require remote commands to set the range. To communicate
between the PC and the Logger, the 173x driver must be installed. This driver is installed when the Fluke
Energy Analyze (FEA) software is installed.
To find the COM port:
1. Make sure the instrument is powered and connected with the PC.
2. On the PC keyboard, press W
3. Type devmgmt.msc and press ENTER.
4. Go to Ports (COM & LPT) and double-click to open the sub-tree.
5. Find Fluke 173x Power/Energy Loggers. The port number is shown in parenthesis after this text, for
example, COM6.

How to Use the Spreadsheet
The Excel workbook, Fluke173x-ExcelTool_Vx.xx.xlsm, (ExcelTool-available at www.fluke.com),
communicates with the Logger using remote commands through the USB ports. The Excel file supports both
the 5520A and 5522A Calibrators.
The Excel file uses macros. Make sure execution of macros is enabled on your PC.
Make sure that Fluke Energy Analyze is closed when using the Excel program. After
closing Energy Analyze, disconnect and reconnect the USB cable or turn off and turn
on the instrument to reset the communication protocol in the instrument.
You must know which COM port the Logger uses to communicate.
To find the COM port:
1. Make sure the instrument is powered and connected with the PC.
2. On the PC keyboard, press W
3. Type devmgmt.msc and press ENTER.
4. Go to Ports (COM & LPT) and double-click to open the sub-tree.
5. Find Fluke 173x Power/Energy Loggers. The port number is shown in parenthesis after this phrase, for
example, COM6.
The workbook contains sheets for various tasks:

Basic Instrument Setup for all Verifications
The Fluke173x-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.
Connect the Logger USB to the PC and start a communication program. See USB Communication.

4. Select Measurement Setup as no voltage transformers used.

Accuracy Verification Procedure
The procedure verifies the Power Logger accuracy at ambient temperature 23 °C ±2 K (intrinsic error).
A complete accuracy verification of the Fluke 173x consists of:
• Voltage Measurement
• Current Measurement
• AUX Measurement
• Optional Flexi or Current Clamp Verification
Voltage Measurement
1. Select the setup (see Basic Instrument Setup for all Verifications on page 22).
2. Connect the VL1730 "N" lead to the calibrator NORMAL LO.
The Logger must be on battery power with ≥50 % charge.
3.
4. Connect the calibrator NORMAL V output to the VL1730 L1+L2+L3 leads.
5. Sequentially set the calibrator to the voltages indicated in Table 10 and check that the Logger reading is
between the limits.
6. Do this for all ranges indicated in Table 10:
• set the calibrator to supply a 57.0 Hz sine wave for all voltages
• wait until each reading has stabilized
The spreadsheet is the first choice for readings. Readings will have more resolution from the
spreadsheet.
7. Push to select the Power Logger voltage display.

Current Measurement
Fluke recommends using a divider with 30 Ω across the Logger input and 10 kΩ in series with high side of
the input:
• Fluke PN 2114858 (10 k)
• 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.
Be careful when you set the calibrator output voltages. High voltages applied to the
current input will damage the Logger.
1. Connect the Voltage-to-Current Input Cable Assembly to the Power Logger current probe input. See Table 4.
2. Connect the VL1730 "N" lead to the calibrator AUX LO.
Connect the calibrator AUX HI output to the VL1730 L1+L2+L3 leads.
3.
4. Stack the calibration cables, PN4293284, together: red to red and black to black.
5. Plug the attenuator into the calibrator Normal HI and LO.
6. Connect the stacked calibration cables, PN4293284, to the attenuator. Connect the black leads to
NORMAL LO.
7. For all ranges in Table 11, set the calibrator to the voltages indicated in the given order. Check that the values
are between the limits.

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
3. Connect the calibrator AUX jacks:
• For the 5500 Coil verification (see Table 13) connect the 5500 coil to the calibrator and the black jack to
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.

6. Set the calibrator to source 100 V @ 57 Hz and the appropriate currents for the current probe under test.
• For the 5500 Coil verification (see Table 13) when the 20 A jack column is “No” when the AUX HI
connections should be used; “Yes” when 20 A connection is required. The calibrator switches to the
Standby mode when the jack requirement changes.
• For the 52120A Coil verification (see Table 14) source the voltages listed in the table on the AUX jack,
maintaining the 100 V @ 57 Hz out the Normal jacks.
