Shutdown Procedure

1. Disconnect the voltage cords and clamp-on sensor from the measured line.
2. Turn off the power to the 3169-20/ 21.
3. Disconnect the power cord from the AC outlet.
4. Remove the PC card from the 316920/21 and analyze  the saveddata on PC.

2.3 Measurement Preparations

1. Connecting the Power Cord
   • Before turning the product on, make sure the source voltage matches that indicated on the product’s power connector. Connection to an improper supply voltage may damage the product  and present an  electrical hazard.
   • To avoid electric shock and ensure safe operation, connect the power cable to a grounded (3-contact) outlet.1. Connect the power cord to the AC power inlet.
   2. Plug the power cord into the AC mains outlet.

2. Connecting the Voltage Cords
   Connect the voltage cords to the product first, and then to the active lines to be measured. Observe the following to avoid electric shock and short circuits.
   • Voltage cord should only be connected to the secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made  to the primary side of a breaker, because unrestricted currentflow could cause a serious accident if a  short circuitoccurs.
   • Do not allow Do not allow the voltage cable clips to touch  two wires at the same time. Never touch the edge of themetal clips. Never touch the edge of the metal clips.
   • Voltage input terminals U1, U2, and U3 are common to the N terminal and are not insulated. To avoid the risk of electric shock, do not touch the terminals.
   • For safety reasons, when taking measurements, only use the 9438-03 VOLTAGE CORD provided with the product.
   • The supplied voltage cords consist of one each red, yellow, blue and black cords. Connect only the cords actually needed for measurement. Cords not being used for measurement should be disconnected.Voltage input terminals
   Connect the 9438-03 VOLTAGE
   CORD to the voltage input terminals of the 3169-20/21.Insert plugs all the way in.

3. Connecting the Clamp-On Sensor
   Connect the clamp-on sensors to the product first, and then to the active lines to be measured. Observe the following to avoid electric shock and short circuits.
   • Clamp sensor should only be connected to the secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs.
   • When the clamp sensor is opened, do not allow the metal part of the clamp to touch any exposed metal, or to short between two lines, and do not use over bare conductors.
   • To prevent damage to the product and sensor, never connect or disconnect a sensor while  thepower is on.
   • The current input terminals of the 3169-20/21 are not insulated. To avoid the risk of electric shock, only use the specified optional clamp-on sensor.Current input terminas
   Connect the 9661 CLAMP ON SENSOR to the current input terminals of the 3169-20/21.
   3169-20/21 Current input terminal connector guide pins Align the slots in the BNC plug with the guide pins on the connector at the instrument side, then push and turn the plug clockwise. (to unplug the connector, push the plug and turn it counterclockwise before pulling it apart.)
   When disconnecting the BNC connector, be sure to release the lock before pulling the connectors apart. Forcibly pulling the connector without releasing the lock, or pulling on the cable, can damage the connector.

4. Inserting a PC Card
   Use only PC Cards sold by HIOKI. Compatibility and performance are not guaranteed for PC cards made by other manufacturers. You may be unable to read from or  save data to such cards.
   • The PC card or the instrument can be damaged if the card is inserted forcefully in the wrong direction.
   • Never eject a PC card while it is being accessed by the instrument. Data on the PC card may be lost.Open the cover and insert the PC card with the arrow facing up and in the direction of the PC card slot, as far as it will go.
   ❖ Instruction manual 7.2 “Using a PC Card” (page 117)

5. Turning the Power On
   Before turning the product on, make sure the source voltage matches that indicated on the product’s power connector. Connection to an improper supply voltage may damage the product and present an electrical hazard. Turn the POWER switch ON ( 1 ).
   As soon as the power is turned on, the self-test screen appears. Upon completion of the self test, display switches to the measurement screen.

2.4 Connect to the Line to be Measured

1. Setting the wiring details
   Set the 3169-20/21 to measure a three-phase 3-wire 200 V line (50 Hz, 50 A load) using the 9661 CLAMP ON SENSOR (500 A rated).
   (1) Set the wiring to “3P3W2M.”
   SET UP
   NEXT SCR
   Press the SET UP key to display the setting screen.
   Press the F5 (NEXT SCR) key to display the measurement setting screen. Move the cursor to “WIRING.”
   change Press the F1 (change) key to display the selection window. Select “3P3W2M”(Three-phase 3-wire, 2-power-meter method) by using the cursor key.
   select Press the F1 (select) key.
   (2) Make sure the number of circuits to be measured is set to “X1 (1 circuit).”When multiple circuits of the same voltage system (the same transformer) are to be measured, use a preset between X2 (2 circuits) and X4 (4 circuits).

(3) Make sure the synchronization method (sampling) is set to “PLL.”(4) Make sure the frequency of the line to be measured is set to “50 Hz.”(5) Make sure the reactive power-meter method is “OFF.”(5) Make sure the displayed data averaging times is set to “1.”(6) Set the voltage range to “300 V.”Move the cursor to “VOLTAGE RANGE.” Select “300 V” using the function keys.
(7) Make sure the VT (PT) ratio is set to “1.”Set the VT (PT) ratio, if necessary.
(Example)
When the primary voltage is 6.6 kV and the secondary voltage is 110 V, the VT ratio is 60 (6600 V/110 V). In this case, as the rated measurement voltage is 110 V, set the voltage range to 150 V.
(8) Make sure “9661” is selected as the clamp-on sensor to be used.(9) Set the current range to “50 A.”Move the cursor to “CURRENT RANGE.” Select “50A” using the function keys.
Selectable current ranges vary according to the clamp-on sensor used.
Clamp-On Sensor and Current Range:

(10) Make sure the CT ratio is set to “1.”Set the CT ratio, if necessary.
(Example)
When the primary current is 100 A and the secondary current is 5 A, the CT ratio is 20 (100 A/5 A). In this case, as the rated measurement current is 5 A, set the current range to 5 A.
