Only the size of an A4 sheet of paper, the HIOKI LR8400-20 Series is the realization of our goal to build a logger that provides the existing functionality of a multi-channel data logger in a portable format. The new model comes with 30 channel capability as standard, to which another 30 channels can be added. All input channels for measuring temperature, humidity, voltage, and impedance are isolated for safety, culminating in a powerful multi-measurement system that also offers pulse and logic inputs. Long-term logging is coupled with the capability to protect data against unexpected power outages and other problems for stable recordings over an entire year.

In fuel cell, electric automobile and other development

Multi-channel measurements - In the development of fuel cells, multiple power-generating cells are connected to form a stack. Independent measurements of each cell require multi-channel measurements of DC voltage, DC current, temperature and other parameters. The LR8400-20 Series comes with 30 channels as standard, which can be expanded to 60 channels.
 

High withstand voltage

The HiLOGGER measures not only fuel cells, but also batteries for UPS (uninterruptible power supplies) devices used in buildings as well as batteries consisting of cells and packaging connected in stacks that require multi-point measurements. In such measurements, high voltage for the whole stack is applied between channel-to-channel and channel-to-ground. Only a measuring instrument with isolated inputs and high-capacity withstand voltage characteristics can endure this.

High-speed sampling - In the development of automobiles such as electric vehicles (EV) and plug-in hybrid vehicles (PHV) that use motors for propulsion, abrupt changes in load need to be measured. This makes the multi-channel, high-speed 10 ms sampling capability of the LR8400-20 Series an indispensable feature.

A compact A4 size enhances mobility

A compact A4 size footprint makes it ideal for use in virtually any environment.

Accurately capture any phenomena you want to measure

10 ms high-speed sampling

The development of hybrid and electric automobiles requires instruments that can measure abrupt load changes. Channels 1 to 15 provide 10-ms sampling and channels 16 to 30 provide 20-ms sampling. This channels allow you to track waveforms not possible with earlier models.

Enhanced noise suppression

A digital oversampling fi lter function reduces inverter switching noise and 50/60 Hz hum noise, a concern in earlier models, during recording.

5.7 inch TFT LCD display is easy to view even at an angle

The LCD has a wider visual angle and is larger (5.7 inches, 640 × 480 dots) than the STN LCD in our previous model (8420-51s) to facilitate observation of waveforms on multiple channels.

Store data securely for more than 1 year

Compatible with USB memory devices

For even greater convenience, the HiLOGGER now provides support for USB memory devices. Measurements can now immediately be written to a USB memory device in real-time. USB memory devices are also a handy means to transfer data to a PC.
Saving data to CompactFlash (CF) card
Use only HIOKI CF cards, which are manufactured to strict industrial standards, for long-term storage of important data.

Cards can be replaced during real-time recording

This function has been provided to enable removal of cards during recording to allow the user to analyze the data recorded so far.
This makes it possible to replace USB memory devices and CF cards during real-time recording without having to stop measurements.

A host of useful functions and features

Up to two additional 15 channel input units can be added

The need for more measurement channels can be met even after purchasing the instrument. The instrument comes with 30 channels as standard, but another two 15 channel input units can be added to expand the total number of channels to 60.

Input setting screens with waveform monitoring

The HiLOGGER adopts the setting screens that earned its sister model (8430-20) a reputation for user-friendliness. Range settings, warnings, triggers, waveform processing and other measurement input settings can be taken in at a glance.

Alarm output

The HiLOGGER outputs a signal when alarm criteria are satisfi ed and also sounds a buzzer. Four systems are provided as standard and separate criteria can be set for each input source enabling OR and AND criteria between channels.

Protection of files being stored on external storage media
An internal high-capacity capacitor will provide enough power to store any data at risk on a CF card or USB memory device should a sudden power outage occur during long-term storage. This reduces the risk of data loss and corruption of the fi le system. Measurements will resume as soon as the power returns.

Real-time processing functions

The HiLOGGER comes with [four arithmetic operation] functions for processing between channels. Data processed in real-time can be displayed in graph form. In addition, processing results for 30 channels are stored in internal memory and can be handled as data for independent input channels.
Records average values every 30 minutes
The HiLOGGER contains a [time-span processing] function. The instrument will save processing data as text data for a preset time period in real-time.

Simultaneous recording to storage media and PC

Measurement data can be simultaneously saved to external storage media and a hard disk on a PC connected to a network to reduce the risk data loss.
USB and LAN connection for easy setup
The supplied Logger Utility software allows you to set up the logger from a PC. Setup could not be easier. Just follow the numbered procedures to set up the instrument.

Bundled user-friendly software for PC analysis

Control of measurements from a PC screen

Connect the PC to the HiLOGGER using USB or via LAN. Use the supplied Logger Utility software to record data on a PC in real-time. Scroll backwards through the displayed trend graph window to view past waveforms even while recording. Up to fi ve HiLOGGERs can be connected to one PC.

Analyze after measuring

Our new “dual-knob function” greatly simplifi es data analysis. Two separate waveform windows are provided, with the displayed waveforms showing different time-axis scales (time bases). This capability substantially simplifi es long-term data analysis. (Patent pending)

Remote control through HTTP server function
Without the need to install additional software, you can use an ordinary web browser on your PC to set up the HiLOGGER, acquire data and monitor data on the screen.
Data acquisition via FTP
FTP allows the PC to acquire fi les stored on HiLOGGER storage devices or measurement data in internal memory.
Data transfer via FTP
Data saved in real-time to storage media can be automatically transferred to an FTP server started from the PC either at regular intervals during measurements or when measurements end.
Be informed via E-mail
Your PC or mobile device is notifi ed of storage media full, internal memory full, stop trigger invoked, alarm occurrence and other events via E-mail.
