Fax modem function
With the OR300E
you can set up a wide-area
data collection network over telephone lines using
commercially available fax/modem PC cards. This
eliminates constraints on the physical distance between
the oscillographic recorder and the monitoring station.
Temperature Measurement
In addition to the direct measurement capability (up to
500 Vrms), the new OR300E includes a temperature
input adapter (788041-1) that works with type
K thermocouples. The adapter is powered by the
OR300E, so there’s no need for a special power
supply when you use the recorder in the field or take
long-duration measurements. The OR300E has
a special temperature input adapter range (see the diagram
on the right) for easy setup.

Data Recorder Functions
using a PC card
The OR300E lets you write measurements continuously and in real time to an ATA flash memory
card (PCMCIA card). This means internal memory capacity is no longer a limitation on total recording time*1,
allowing you to take long-duration measurements previously handled by data recorders. You can also display
measured data stored in flash memory on the OR300E display for easy field checks.*2 In addition,
ACRAWin32 is available to assist you in making reports when handling massive amounts of data.
*1 : Maximum sampling rate: 1.6 kS/sec;
*2 : Displays 128 kdata/ch steps
Four-mode power supply
for field use
In addition to working with a 3.5-hour* rechargeable
battery (788021), the OR300E/OR300E also can be
powered by an AC adapter (100–240 V), DC adapters
(12 V/24 V/48 V), and alkaline batteries. Choose the
power supply type that best fits your needs.
Powerful Trigger Functions
The OR300ESeries provides powerful trigger functions for reliable measurement of monitored parameters.
In Normal Trigger Mode, triggers are set for the rise and fall levels. Wave-window Trigger Mode allows you
to monitor for power supply waveform abnormalities in real time. In addition, pre-trigger settings may be set as
desired.
Sharp Display, Calculation Functions and High-Quality Recording Functions
Measurements are clearly displayed on a 5.7-inch backlit LCD display. You can view captured data and print out just the areas
you need. Other capabilities include real-time recording, X-Y display and recording, and transient measurement (memory
sampling when a trigger is sensed during real-time recording). |
