1)If intend to make the Transient Capture measurement it
should set the transient voltage level ( high level, low
level ) at first , the setting procedures, please refere to
chapter 4-5-9 and chapter 4-5-10.

2)Press " Transient Key " ( 3-32, Fig. 1 ) will enter to
Transient Capture screen, insert the SD memory card
then press the " REC Button " ( 3-9, Fig. 1 ) will make
the measuremnt, refer as the Screen 1

3)Definition :
a. SWELL :

Vrms > ( Vref + ( Vref * SDVP% ) )

b. DIP

Vrms < ( Vref - ( Vref * SDVP% ) )

c. OUTAGE

Vrms < 30 V to 40 V.

d. Line item :

* V is the code show the all phase V1, V2, V3 ever

happen the transient event.

* V1, V2, V3 is the code that show each phase V1,

V2, V3 ever happen the transient event.

* Refer to Screen 2.

4)Press the " REC Button " will exit the Transient Capture
function as Screen 3.

5)One screen can show 13 transient events.
One file can record 99 transient events.
When the transient even more than 13 no, then
press the " Button " , " Button " can show more▼▲
transient events. If the transient events less than 13 no.,
" Button " , " Button " are disable.▼▲

Screen 1 ( 5-10 )

Remark :

When press " 1Φ 3Φ Button " ( 3-2, Fig. 1 ) once in insequence,
it can switch to the the transient measurement of different
Wire connections such as 1P2W, 1P3W, 3P3W, 3P4W.

Caution :

Remove test leads before

opening the battery cover

or housing case !

6-1 Cleaning

Caution :

Cleaning - Only use

the dry cloth to clean

the plastic case !

6-2 Replacement of batteries

1)When Display show the " LOWBAT " indicator ( ref. 5-15
page 67 ), it should change the batteries.

2)open the " Battery Cover " ( 3-19, Fig. 1 ) away from the
instrument and remove the battery.

3)Replace with batteries ( DC 1.5V, AA/UM-3 battery
X 8 PCs ) and reinstate the cover.

* When install the batteries, should make

attention the battery polarity.

4)Make sure the battery cover is secured after changing
the batteries.

7. RS232 PC SERIAL OUTPUT

.

The instrument is provided an 3.5 mm dia. phone socket
( 3-16, Fig. 1 ) for RS232 computer interface socket.

The connector output is a 16 digits data stream which
can be utilized to the user's specific application.

A RS232 lead with the following connection will
be required to link the instrument with the PC
serial input.

Meter PC

(3.5 mm jack plug) (9W 'D" Connector)

8. Download the saving data from the

SD card to the computer ( EXCEL
software )

1)After execute the Data Logger function, take away the
SD card out from the " SD card socket " ( 3-15, Fig. 1 ).

2)Plug in the SD card into the Computer's SD card slot
( if your computer build in this installation ) or
insert the SD card into the " SD card adapter ". then
connect the " SD card adapter " into the computer.

3)Power ON the computer and run the " EXCEL software ".
Down load the saving data file ( for example the file
name : 3P401001.XLS, 1P201001.XLS, 1P301001.XLS,

3P301001.XLS........) from the SD card to the

computer. The saving data will present into the EXCEL
software screen ( for example as following EXCEL data
screens ) , then user can use those EXCEL data to make
the further Data or Graphic analysis usefully.
