1. Instrument overview
Following explains about the features and functions of this instrument.
1-1 Features
This instrument is a clamp power meter, and can be used for various
wiring systems. As to single-phase 2-wire circuit, this instrument can
measure up to 3 loads, that is; three in one.
This instrument can measure fundamental electric power factors, namely,
instantaneous value and integration value. Moreover, demand measurement,
which is important to control electricity, is available.
Each data can be saved to CF (compact flash) card or PC by USB
communication.
● Safety design
Designed to international safety standard IEC61010.
● Wiring
This instrument supports:
single-phase 2-wire (
1ch ), single-phase 2-wire ( 2ch ), single-phase 2-wire ( 3ch ),
single-phase 3-wire, three-phase 3-wire, three-phase 4-wire.
● Measurement and calculation
This instrument measures and calculates:
voltage(RMS), current(RMS), active/ reactive/ apparent power, power factor,
frequency, current flowing on the neutral line(only at three-phase 4-wire)
active/ reactive/ apparent electric energy.
● Demand measurement
With this instrument, you can control the usage of electricity easily so as not
to exceed the target (contract demand) electricity.
● Saving the measured data
Instantaneous value can be saved whenever the key is pressed.
Integration value and demand value can be saved in wide cycle from 1 sec.
to 1 hour.
In addition, max and average instantaneous values can be measured at
Integration/ demand measurement cycle.

MODEL6300 1.2
MODEL6300 Section1Instrumentoverview
Section 1
●Power supply
This instrument operates either with AC power supply or battery.
In the event of service interruption while the instrument is operating with
AC power supply, power to the instrument is automatically switched to the
battery set in the instrument.
Batteries can be also used for backing up the data.
● Large display
Any three measurement items can be displayed at once.
(e.g. Current, Active power, Power factor)
● Customizing display
Three measurement items can be switched to any desired items by
customizing display screen.
● Backlight
Backlight function to view the test results in dimly lit areas.
● Clamp type, light & compact design
Can clamp the measured object easily.
Easy-to install, portable.

Section1Instrumentoverview MODEL6300
1-4 Outline of demand measurement
Depending on countries, a consumer of large electricity will make a demand
contract with a power company. Following explains demand contract with
taking Japanese demand contract as an example.
● Demand contract
Demand contract is to be made between electricity user and power
company, and the basic charges for electricity is decided based on the
max power for 30min, which is measured with the recorder (demand meter)
installed by a power company.
Suppose you made the contract at 500kW/year, and the recorded demand
(for 30min) was max 600kW on January 15. (100kW exceeded against
500kW)
Then, how much you try to save electricity, the basic charge will be
calculated based on 600kW for one year from February. One year later,
when the recorded demand as of February is 300kW, the contract demand
will be changed to 300kW. But if 600kW is used in March, the contract
demand will be changed to 600kW for another year. In order to avoid such
demand charges, large factories are controlling demands.
● Status of demand contract
In past days, only the customers who use electricity of 600kW or more used
to make a demand contract. But now power companies install demand
meters for all the electric customers who have a high voltage
access-to-electricity of 70kW or more.
(For the equipment of 70kW or less, demand contract is to be made based
on the distribution board for it.)
● Effect of demand control
Like mentioned in above passage, if the demand can be reduced from
600kW to 300kW, you can save:
(600 kW -300 kW) x (price per kW) x power factor
Demand control works effectively in the country with high electricity charges.
● Demand measurement function
With this instrument, you can easily control the usage of electricity so as not
to exceed the target value (contract demand). However, a demand meter,
which is installed by a power company, and this instrument may not match
completely due to time-lag.
Recording the max electricity within the specified period with this instrument
makes sense to control the electricity.
