3.1.1. Enviroment and Handling
The Graphics Recorder Type 2313 is designed for indoor use at temperatures from
+10 to +40°C (+50 to +104°F) and humidities up to 90% RH (non-condensing). For
safe operation avoid use in volatile environments and before each use of the instru-
ment check that it is set to match the available supply voltage as described in section
3.1.3.
To ensure reliable operation of the 2313, it is important that the following be observed:
•
When first using the 2313 keep it powered for approximately 14 hours to prevent
loss of data stored in its continuous memory.
•
If the 2313 is not to be used for 4 weeks or more, disconnect the internal Ni-Cd
battery used to power its continuous memory (see section 3.1.4).
•
For optimal reproduction of printed data regularly clean the print head of the 2313
as described in section 3.3. Avoid use of chemical cleaning agents and sharp
tools, as these can damage the print head.
3.1.2. Rack Mounting
The 2313 may be used free-standing on its four plastic feet or, with the addition of the
Flanges KS 0024 available, may be mounted in a 19 inch instrumentation rack. The
flanges fasten via two screw holes at the front of the instrument side panels. These are
accessible on easing back the bottom panel which is fastened by two screws on the
rear of the instrument, plus removing the plastic corner pieces and sliding out the
grooved plastic strips at the front of the side panels. Before releasing the bottom panel
ensure that 2313 is disconnected from the mains supply.
3.1.3. Connection of Mains Supply
Before connecting a mains supply, the following mains voltage setting and fuse checks
should be carried out to ensure safe operation of the instrument.
Mains Voltage Setting
The 2313 may be powered from 100, 115, 127, 200, 220 and 240 V
±
10% (50 to 60 Hz)
single phase AC mains lines. To select the correct mains voltage setting, use a small
screwdriver to push in and release the fuse holder at the centre of the Mains Voltage
