2.1 Instrument description
The pen recorder provides 1, 2 or 3 chan-
nels for recording; the channels are isolated
from each other by optocouplers. Channel 1
can be used to write text in addition to the
signal trace. All three channels are zeroed
using Hall sensors.
A 24-place 5x 5 LED dot matrix display is
available for signal indication and program-
ming. Operation is by eight keys on the in-
strument front and via a setup program us-
ing a PC. The configuration data are stored
permanently in EEPROM.
Input signals include resistance thermome-
ters, resistance transmitters, thermocouples,
standard current and voltage signals. The
necessary linearisation is performed auto-
matically. Eight logic inputs are available for
operating functions. An external relay mod-
ule ER8 for rail mounting supplements the
pen recorder by eight switching outputs.
A 2-wire transmitter can be operated from
an isolated supply. The watchdog monitors
the recorder operation and triggers a restart
in case of a fault. On a power failure the
real-time clock is supplied by a lithium bat-
tery or a storage capacitor.
A summary of all recorder parameters is
given in the Appendix (
Section 12.6).
