1.1 Product Overview and Features
Record, verify, and notate
measurement results in the field
Measurement results are recorded on paper, allowing
them to be easily verified. You can also make notes on the
paper in the field. Additionally, the instrument can measure
voltage output from other equipment, allowing it to be used
in maintenance applications such as corrosion prevention
systems. It can also record analog output, for example
from sensors and physics or chemistry instruments.
Assess changes in easy-to-see
color waveforms by watching
pen movements
The instrument can use red, green, and blue
pens (option). Waveforms are easy to see, even
outdoors, and can be stored for extended periods
of time. Additionally, you can assess waveform
changes in real time simply by watching the in-
strument’s pens as they move.
Preserve important recordings
Record with the front cover open to protect
recording paper from dirt on the ground.
Record with the front cover closed to keep out
dust and wind.
You can also use the included drip-proof vinyl
cover to protect the instrument from water
droplets and dust.
Select the power source
according
to your location
The instrument can be operated us-
ing either the AC adapter or dry-cell
batteries.
Easily compare and
verify results on paper
You can easily discover changes
and abnormalities by comparing
recordings with previously record-
ed waveforms.
Operating environment
This instrument is intended for use indoors. If you use the instrument in locations with an
excessive amount of dust or sand, the pen operation could malfunction. Close the front cover,
put the drip-proof cover on the instrument, and then load fanfold paper into the instrument.
