A.
Power-Up Test
Charge the instrument for at least one hour before performing
this test. Proceed with the power-up test as follows:
1.
Disconnect the AC adapter from the instrument.
2.
Remove any cassettes installed in the instrument.
3.
Turn the instrument on and verify proper power-up.
4.
The instrument performs initial self-test during power-up;
and, if it detects any problems, it will indicate a fault.
5.
Check audio and keypad operation by ensuring there is a
soft beep for each key press.
6.
Press any key and ensure the LCD backlight turns on.
Note:
For a complete memory self-test, the instrument should be
turned on for a minimum of 10 minutes for the Model 2860 and
18 minutes for the Model 2863 or 2865 instruments. It is not
necessary for the unit to be pumping to perform this test. If
operating on battery power, a cassette must be installed in at least
one of the channels and that channel put in standby mode;
otherwise, the instrument will automatically shut off after five
minutes of inactivity.
B.
AC Power Test
1.
Turn on the instrument without the AC adapter attached.
2.
Install a primed cassette in each pump channel.
3.
Start all channels (at any rate). Verify the green LED on each
channel blinks during operation.
4.
Attach the AC adapter to the pump. Verify that the
instrument beeps three times when the connector is
properly installed. Verify that the green plug-shaped light
on the side connector panel is lit and does not blink if you
wiggle the connector.
5.
Verify that the green LEDs for each channel key (A, B and C)
are steadily illuminated. If they are blinking, then the
instrument is not recognizing that AC power is connected.
This test verifies the proper functioning of the cassette and latch
sensors, as well as the latching mechanisms. Repeat the
following procedures for all three channels (A, B and C).
1.
With the instrument off, remove any cassettes that are
installed in the instrument.
2.
Turn on the instrument.
