Records ten times* faster, yet small and light enough for the palm of your hand! *compared to the HIOKI 8420-51 series
Personal Data Logger with Ten Isolated Channels
■ Provides ten electrically isolated analog input channels for measuring voltage
and temperature, plus four pulse-counting input channels. The isolated inputs alleviate
constraints when measuring temperatures in live electrical circuits while minimizing
interchannel interference.
10 ms scanning of all channels provides rapid sampling capabilities
To meet the demand for measuring sudden changes in load, this model tracks
waveforms that earlier 100 ms models could not.

• Maximum recording time is inversely proportional to number of recording channels.
• Because the actual capacity of a CF card is less than that indicated, and because the header portion of waveform files is not included in capacity calculations, expect actual
maximum times to be about 90% of those in the table.
• "★" Exceeds 365 days.

Isolated, high-speed-sampling data logger
electric/hybrid vehicles
Highlights - Fast, 10 ms sampling even while measuring on all channels - Measurement circuit includes effective noise suppression -
■ 10 ms Sampling and Recording Across All Channels
Abrupt changes in load need to be measured during
development of electrical vehicle systems such as in recent
hybrid cars, for which multi-channel, 10 ms sampling is
essential. This HiLOGGER can track waveforms that could
not be followed with the 100 ms sampling interval previously

10 ms (upper trace) and 100 ms sampling (using the supplied Logger
Utility program)
Measurement comparison of 5 Hz square pulse waveform with 10 ms
(upper trace) and 100 ms sampling (using the supplied Logger Utility
■ Enhanced Noise Suppression
Measurement involves the deployment of a deltasigma type A/D converter. Suppress inverter switching
noise and line-frequency hum by digital filtering with the
HiLOGGER's proprietary oversampling technology.
Note: Optimum noise suppression is obtained for recordings at least two seconds
■ Ten Isolated Analog Input Channels
There’s no need to worry about differing potentials of
measurement objects when measuring temperature
and voltage. All ten analog channels are isolated.
Channel-to-channel: 60 V DC max.
Even when measuring temperature and voltage at the
same time, interchannel interference and electric shock
hazards are eliminated. The four pulse channels are
ideal for counting revolution pulses to measure rotation
Note: Pulse inputs share common ground.
Channel-to-ground: 60 V DC max.
