5. Press the Calibrate button. This saves the current
distributor arm position as “home.”
Note
The arm must be at the stop when the Calibrate button is
pressed. The calibrate function always saves the arm’s current
position as "home."
6. Enter the bottle number to which the sampler should move
the arm. Press Enter and the distributor will run.
7. The sampler reports the new distributor arm position. Ver-
ify that the arm is aligned over the correct bottle.
8. The sampler then asks for the next bottle position. Enter a
bottle number and press Enter, or press the Stop button to
exit the test.
9. From the standby screen, reenter the code 82253 (TABLE)
to exit Calibrate mode. It is important to exit Calibrate
mode prior to operation to avoid errors during the running
of a program.
If the sampler displays DISTRIBUTOR JAMMED , DISTRIBUTOR
ERROR , SLOT CODE ERROR , DISK ERROR , or BELT TOO
LOOSE , verify that the arm movement is not obstructed. Clear
any obstructions such as bottles not fully seated in the rack or an
incorrectly installed discharge tube, then perform the
TEST DIS-
TRIBUTOR diagnostic again from step 1. If you don’t find obstruc-
tions to the distributor arm movement, contact your authorized
Isco service facility or the Teledyne Isco factory.
