A pen and a chart have already been installed for your conve-
nience. All you need to do to start using your CR20 recorder with
the settings listed above is follow these quick start instructions:
1. Plug in AC adapter.
2. Hook up your 0 - 5 Vdc transmitter (See "Instrument Anatomy"
on p. 3, Fig. 2).

Operating Information

Transmitter/Sensor
A powered transmitter is required to operate the CR20. Any pow-
ered transmitter with a 4-20mA, 0-20mA, 0-5Vdc output signal
may be used. To connect a transmitter to the recorder, locate the
terminal block on the back on the recorder (See "Instrument
Anatomy" on p. 3, Fig.2). Connect the positive wire of transmitter
to positive terminal (left) of recorder and the negative wire of
transmitter to negative terminal (right) of recorder. Tighten screws
in terminal block to hold in transmitter wires.
It is vitally important to be sure the voltage/milliamp switch in the
back of the unit, together with dip switch #3 properly corre-
Note: Be sure to observe proper polarity when connecting wires
from transmitter.
3. Set the appropriate time by inserting a coin into the groove in
the chart hub and turning clockwise until the correct hour and
day on the chart is referenced to the timing clip (See
"Instrument Anatomy" on p. 3, Fig 1).
4. Remove the protective pen cap from red pen and insert on Pen
Cap Holder.
5. Press the "On/Off" key and the pen will move to the current
reading: a powered transmitter must be used to receive a read-
ing.

sponds to the transmitter used (i.e.) if using a 4-20mA transmitter
be sure the voltage/milliamp switch in back is on mA position and
#3 dip switch set in "on" position). If the unit is receiving too
much power from a transmitter, the unit will make a loud beeping
sound. Disconnect the transmitter immediately and check switch
settings.
Recorder Power Supply
We recommend using AC power with four "D" batteries installed
as a back-up power source. This ensures that your recording will
not be interrupted when there is a power failure. The AC adapter
plugs into the back of the recorder beneath the alarm.
