l Recording interval of 100 μs to 1 min l Waveform data is saved directly in a binary format to a CF card or USB memory. 

- Maximum recording time is inversely proportional to number of recording analog channels. 

- Because the actual capacity of a CF card is less than that indicated, , expect actual maximum times to be about 90% of those in the table. 

- " ★ " exceeds 1 year. 

• Proper operation is not guaranteed for extended recording periods (one year or longer). This type of operation impacts the product’s warranty period and service life.

Four channels of isolated CAT III 600 V input The MR8880 can measure the voltages at different contacts without the need for a differential probe. 

Thanks to its 14-bit, high-resolution A/D converter and the combination of a high-sensitivity 10 mV/div range and a 5 Hz filter (for noise rejection), the MR8880 can deliver stable measurement of sensor output. 

The MR8880 is capable of mixed recording of RMS values, DC voltage, and logic signals, allowing it to simultaneously record data describing the interrelationships between equipment power supplies and UPS output and control signals.

## Functionality and Performance 

The MR8880 delivers convenient functionality designed to maximize ease of use along with exceptional performance. See how this instrument can transform your concern and discontent to peace of mind and satisfaction. 

Take home data for later viewing on a computer 

Data can be saved directly to external media. 

- l In addition to CF cards, the MR8880 can store data on handy USB memory sticks. 

- l Data can be saved in real time to external media (at up to 10 kS/s). 

- l External media can be switched while measurement continues. 

If the recording interval is set to 100 μs, media must be swapped outwithin 20 seconds. 

- l External media is protected in the event of an unexpected power outage during measurement. 

By backing up the internal power supply until processing to save data to the external media completes, the instrument enables highly reliable data collection.

Use only HIOKI CF cards, which are manufactured to strict industrial standards, for long-term storage of important data. 

_Note: Operation of non-HIOKI CF cards is not guaranteed_ 

Can the MR8880 withstand the vibrations in a moving vehicle? 

The instrument complies with JIS automotive vibration standards. 

Thanks to its ability to withstand a high level of vibration, the MR8880 can be used to collect data in moving vehicles. Included side protectors further increase the device’s durability. 

Will the screen be hard to read while taking measure- **3** ments outdoors? O What if there’s no power available in the vehicle **4** being tested? 

The MR8880 features a 5.7-inch TFT color LCD that offers excellent visibility, even while taking measurements in an outdoor setting. The display is even engineered for easy viewing in the presence of reflections.a 

## A high-capacity battery is available. 

The MR8880 can be used continuously for 4 hours on battery power. 

## Is the printer easy to use? 

Loading recording paper is a snap thanks to the MR8880’s one-touch loading mechanism. 

Quickly print data on-site.
