Isolating The Problem, System Level; Isolating The Problem Within The Main Unit - Datascope Accutorr Plus Service Manual

4.5.1 Isolating the Problem, System Level

1. Determine if the problem is in the main NIBP unit or one of the add on accessories.
2. If the problem is in the accessory, replace the 9 Volt battery in the temperature module,
and check the recorder unit for correct paper, correct installation and paper jams.
3. If the problem is in the main NIBP and/or SpO
problems first:
If AC power is available, then the green LED adjacent to the front panel On/Off keys
should be illuminated. If not, connect the power cord to live power outlet. If green
LED fails to illuminate, there is a probable power supply malfunction.
Check the battery operation LED. Steady ON indicates battery operation. A flashing
LED indicates a near depleted battery. If the green LED is NOT On, then the battery
or power supply/charger may be suspect.
Confirm correct operating parameters selection, i.e., correct patient size selection,
(Adult, Neonate, Ped.) and NIBP cuffs to match. In units with SpO
sensor is connected to the unit and it is of the proper type/size. Verify the proper
battery charge profile is selected for the installed battery.

4.5.2 Isolating the Problem within the Main Unit

Problems within the main NIBP and/or SpO
supply problems and NIBP and/or SpO
not even turn on, proceed to Power Supply and Battery Tests, otherwise skip to
Diagnostics Test and beyond.
1. Power Supply and Battery test: The main power supply output voltages should be
verified under normal instrument loads. Voltages are shown on the System Block
diagram, which is located in chapter 2 of this manual. Below are the tolerances for the
voltages shown:
5V = 4.9 - 5.1
12.5V = 12 - 13
± 15V = 14.5 - 15.5
2. Perform Diagnostics Test 01 through 12 . Repair or replace circuits or components
that fail to pass the Diagnostic Test.
3. Trend circuits test: Obtain a minimum of five NIBP measurements and simultaneous
SpO and Temperature readings if the Accutorr has those options. Confirm Trend
