Usage Notes

• To avoid damage to the product, do not short-circuit the output
terminal and do not input voltage to the output terminal.
• The channels of voltage input terminals CH1, CH2, and CH3 are
not isolated from one another.To avoid electric shock, do not
touch the terminals. CH4 is isolated from the other channels.
• Note that the product may be damaged if current or voltage
exceeding the selected measurement range is applied for a long
time
• When the power is turned off, do not apply voltage or current to
the voltage input terminals or clamp sensor. Doing so may dam-
age the product.
• To prevent damage to the instrument and sensor, never connect
or disconnect a sensor while the power is on, or while the sensor
is clamped around a conductor.
• When the voltage or current for the power line being measured
exceeds the maximum rated input for this device, use an exter-
nal PT or CT.
• When using an external PT or CT, make sure you use a device
with a minimal phase difference. By setting the PT or CT ratio,
you can read measurement values directly.
Using Potential Transformer (PT or VT) and
Current Transformer (CT)
• To ensure measurements are precise, warm up the device for
at least 30 minutes after plugging it in.
• This device is designed to measure commercial power lines
with a frequency of 50 or 60 Hz. It cannot measure power lines
of other frequencies or power lines where the waveforms are
controlled using an inverter.
• This device cannot measure power lines with superposed
direct current.
• This device uses algorithms to measure values for input volt-
age and current waveforms using (see the specifications). On
devices using different operation principles or algorithms differ,
differences in measurement values may result.
• When the display value for voltage, current, active power, reac-
tive power, apparent power, or the power factor is less than
0.1%, zero is displayed.
