APPENDIX
Thank you for purchasing MPR-601W Digital Power Recorder.
Please read the appendix carefully along with the instruction manual.
●Regarding USB flash drive used on MRP-601W:
One 4GB USB Memory Stick is included as a standard accessory.
Use this memory stick, as there might be possibility that the logging (measurement record)
cannot be done by other USB memory.
USB flash drive made with flash memory, called semiconductor memory.
The semiconductor memory is deteriorated every time wring data; therefore, USB flash drive
has a limit to the number of writing. The longevity of USB flash drive depends on
manufactures, products, individual differences, and usage. Generally, its limit is
approximately 2,000 to 10,000 times.
To extend the life of the USB, in MPR-601W, write to the USB memory together as a single
batch of 50 pieces data logging. If using USB flash drive of a limit of 2,000 times memory,
total 100,000 pieces (2,000×50) logging data can be stored.
If USB flash drive, which has been used for a long time is used on the logging mode, the
logging might be suspended. To avoid unexpected suspension, use never-used USB flash
drive for a long-time measurement on the logging mode.

magnetic field and or electrified, as it may cause mis-movement of the
instrument.
●This instrument does not have the water / dust-proof structure. Do not use this
instrument in the environment with a lot of dust and drops of water, as it may
cause defect of the instrument.
○OPERATION CONDITION & CONNECTlON
△
!WARNlNG
●Take notice that the measurement wetted instrument and or wetted hands may
cause the electrical shock accident. If the water gets into the inside of instrument,
stop the operation immediately.
●In case of measurement for active lines, use protection tools such as rubber
gloves, etc. for the safety and to avoid electrical shock.
●Before input the power, confirm that the voltage indicated on AC Adapter of this
instrument conforms with the power supply voltage to be used.
●Do not apply the voltage except the indicated power supply voltage, as it may
cause the damage to the instrument and or the electrical accident.
●To avoid electrical shock and short-circuit accident, connect the voltage sensor

○CONNECTIONS FOR SECONDARY CIRCUIT & SENSOR CORDS AND
OPERATION OF ACCESSORIES
△
!DANGER
●Connect the input line of POWER RECORDER to the secondary circuit of
breaker. Firstly, connect the clamp CTs and the voltage sensors to the instrument
body and then, connect them to the active power lines.
●Be careful sufficiently, if the clip of voltage sensor removes and touches the
line between two wires, it will cause short-circuit and or electrical shock
accident.
●Apply Clamp CTs only to the coated cables and do not clamp bare cables, as
it may cause electrical shock.
●If excessive current is applied to CT, it will be heated. Use the CT according to
the rating current, as it may cause electrical shock or fire hazard accident.
●Examine the connection cable sensors(including power supply cable) every
time before use(disconnection,contact defect, break of coating, etc.). If there
is anything unusual after examination, do not use it definitely.
△
!CAUTION
●Do not drop the instrument & CTs and or do not give the strong shock.
●Do not put heavy goods on the cables of instrument, CTs & accessories and
do not modify those cables.
●If dropping CTs and or giving strong shock, the joint surface of CTs are
damaged and it may cause wrong influences to the measurement.
●To avoid defect of CTs due to the break of cables, do not bend and or pull the
cables at the base of CTs. Handle them very carefully.
○HOW TO USE
●When direct voltage input, must have clip to the active power terminals. Be
carefully for short-circuit accident, in case of touch between 2 wires at the time of
clipping.
●Do not apply the voltage to the current input terminals.
The instrument will be damaged.
●The max. input rated voltage is AC500V. The excess input than the rated
voltage will cause the damage of instrument and the human accident.
●To avoid defect of CTs due to the break of cables, do not bend and or pull the
cables at the base of CTs. Handle them very carefully.
△
!CAUTION
●Be careful sufficiently. It may cause the damage of instrument in case of the
over input of voltage & current than each measuring range.
●Do not apply the current to clamp CT more than 600A. It may cause the
damage of CT.
●Use the exclusive AC adapter from the accessories. It may cause the damage
of instrument, in case of the use of other adapters than designated.

○CAUTION FOR OPERATING POWER RECORDER
The apparent power & power factor measured by this instrument are calculated by the
operation expressions indicated in this manual and based on the measured voltage(V),
current(I) and active power(P). It may cause the different display value from the instruments
with different operation principle and or different operation expression.
The integral values of this instrument are calculated by the operation on the software from
the measured values of power. It may cause the different integral values from the instrument
with different response speed and or sampling rate, etc.
This instrument is designed exclusively for AC current and cannot measure the line of AC
current mixed with DC.
This instrument has the function for the measurement of frequency but may be unable to do
the correct measurement, in case that the input wave form is extremely distorted.
When using external transformers (PT,CT), it may cause big error in the measurement of
power due to their phase differences. For the accurate measurement, use the PT&CT with
phase difference, as small as possible.
When using PT&CT, use the magnification function and read the measurement value
directly.
