How to troubleshoot a 'Block Probe Failure' on Advanced Instruments Medical Equipment?
A 'Block Probe Failure' on your Advanced Instruments Medical Equipment usually indicates that the block probe has shorted. Check the block probe resistance (2,300 ohms ±300 at room temp.).
What to do if Advanced Instruments Medical Equipment loses power abruptly?
If your Advanced Instruments Medical Equipment experiences an abrupt loss of power, ensure the power cord is firmly plugged into both the wall outlet and the socket on the back of the instrument. If the issue continues, temporarily unplug the power cord and test the outlet with a known working lamp or small appliance. Also, measure the AC voltage supplied at the power outlet. Check the fuses visually or with a continuity checker, and replace blown or incorrect-value fuses with time delay (T) fuses, referring to the instrument serial number label for the correct value. If a replacement fuse also blows, contact our product service department.
Why does my Advanced Instruments Medical Equipment say 'Recalibration Needed'?
The 'Recalibration Needed' error on your Advanced Instruments Medical Equipment indicates that the calibration data has been lost from memory due to a battery back-up failure, installation of a new processor board, corruption of system memory, or new probe bin numbers. Recalibrate the instrument. If the error persists after successful calibration, replace the processor board.
What to do if Advanced Instruments Medical Equipment displays a blank screen or blinking cursor?
If the display on your Advanced Instruments Medical Equipment is blank or has a blinking cursor, it may be due to a voltage drop. Turn the power off and on. If the problem persists, replace the application board.
What to do if Advanced Instruments Medical Equipment shows 'Calibration Out of Range; Repeat'?
The 'Calibration Out of Range; Repeat' message on your Advanced Instruments Medical Equipment means the tested samples did not repeat well enough for calibration. Recalibrate the instrument. Also, check the freeze pulse, sample size and quality, and probe alignment.
What does 'A/D Init Failure' mean on Advanced Instruments Medical Equipment and how to fix it?
The 'A/D Init Failure' message on your Advanced Instruments Medical Equipment indicates that one or both A/D converters lost initialization. Turn the power off and on. If the problem persists, replace the application board. You can also try resetting the baudrate in the SETUP menu.
What causes a 'Cooling System Error' in Advanced Instruments Medical Equipment and how to resolve it?
A 'Cooling System Error' on your Advanced Instruments Medical Equipment suggests the cooling assembly may not be functioning properly. Check the cooling assembly and ensure there is heat transfer fluid in the cooling well. Verify the control signal using LED D16. You might also let the unit warm up and try Power On Diagnostics again.
What does it mean if my Advanced Instruments Medical Equipment says 'Test Cancelled'?
If your Advanced Instruments Medical Equipment displays 'Test Cancelled', it means the STOP button was pressed during the test. Retest with a fresh sample.
What does 'RAM Failure' mean on Advanced Instruments Medical Equipment?
A 'RAM Failure' message on your Advanced Instruments Medical Equipment indicates that the main board has failed. Replace the processor board.
