RT-ZC05B
● Immediately after powering on, this device may be subject to an appre-
ciable offset drift due to the effect of self-heating. To counteract this,
allow the device to warm up for about 30 minutes before carrying out
measurements.
● When performing continuous measurements, it is necessary to be
aware that the offset voltage drifts, depending on factors such as the
ambient temperature.
● Under certain circumstances, oscillation may occur while the power sup-
ply is on. This does not indicate a malfunction. Oscillation can be stop-
ped and operation restored to normal by opening and closing the clamp.
● Acoustic resonance may occur depending on the level and frequency of
the measured current. This does not normally affect measurements
unless a foreign substance such as dust is present on the contact surfa-
ces of the sensor head.
At high frequencies, common mode noise may affect measurements taken
on the high voltage side of circuits. If this occurs, reduce the frequency
range of the waveform measuring instrument, or clamp onto the low-voltage
side of the circuit, as appropriate.
