DNI Nevada Model µ-Test 2000
Incubator 8000 IC / SC / NC
Electrical Safety Test in the USA and Canada according to
CAN/CSA - 22.2 No. 601.1 - M90
1 Visual inspection of basic unit
•Power cord
•Compare fuses to stated ratings on the backside of the Incubator next to the inlet of
the power cord.
2 Safety testing Incubator 8000 IC / SC / NC with DNI Nevada
Model µ-Test 2000
•Fold down flap below electronics module after undoing the two locks.
•Warning: These tests can expose personnel to hazardous electric shock and must
be carried out with caution.
•Note: Do not plug the µ-Test 2000 safety analyzer power cord into a line isolation
monitor as inaccurate readings may occur.
•Ensure that the switch "TEST LOAD" on the backside of the µ-Test 2000 is in the
"IEC 601-1" position.
•Plug the µ-Test 2000 power cord into a live AC receptacle, place the power switch
of the µ-Test 2000 to the "1" or ON position and ensure that the switches marked
"NEUTRAL" and "POLARITY" are in the OFF or CLOSED position.
2.1 Chassis Resistance Testing
•Rotate "MODE" knob to "OHM RESISTANCE" position.
•Attach test lead to "CHASSIS CABLE" input of the tester.
•Plug the Incubator power cord into the test receptacle of the µ-Test 2000.

•Perform 4 tests with the alligator clip attached to the following test items of the
Incubator:
1) Screw at the base plate of electrical
height adjustment (if available) 2) Screw at the metal base plate below Incubator housing
3) Earth chassis connection of the flap
below electronics module 4) Electronics module, earth chassis
connection
•The resistance reading then shown on the µ-Test 2000 is the "Chassis Resistance".
Bend and exercise the power cord to check for intermittent reading.
•Maximum allowable test values:
Chassis Resistance 0.2 Ohm
•Afterwards leave alligator clip at test item 4) or attach the alligator clip to the test
item with the lowest resistance.

2.2 Enclosure Leakage Current (Chassis Leakage Testing)
•Rotate "MODE" knob to "CHASSIS" position.
•Switch on Incubator and allow the unit to complete the self-test.
•Switch on humidity module.
•Set air temperature and humidity higher than measured values.
•Set up the µ-Test 2000 for the following tests by using the switches labeled
"Ground" and "Polarity".
•This is a measurement of the leakage current from the Chassis to earth ground.
•Be sure to pause the "POLARITY" switch in the center-off position before changing
polarity.
•Activate height adjustment (if available) during the following tests.
•Maximum allowable test values under Normal Condition:
Normal Ground, Normal Polarity, Closed Neutral: 100 µA
Normal Ground, Reverse Polarity, Closed Neutral: 100 µA
(According to CAN/CSA - 22.2 No. 601.1 - M90, Sub-clause 19.3, Table IV)
•Maximum allowable test values under Single Fault Condition:
Open Ground, Normal Polarity, Closed Neutral: 500 µA, but not 0 µA
Open Ground, Reverse Polarity, Closed Neutral: 500 µA, but not 0 µA
(According to CAN/CSA - 22.2 No. 601.1 - M90, Sub-clause 19.3, Table IV)
2.3 Earth Leakage Current (Ground Wire Leakage Testing)
•Remove the red lead with the alligator clip from the Incubator.
•Leave all other selections from the previous test the same.
•The Incubator is still switched on.

•Set up the µ-Test 2000 for the following tests by using the switches labeled
"Neutral" and "Polarity".
•Important: Do not press "OPEN GROUND" pushbutton.
•This is a measurement of the leakage current flowing through the ground wire of
the power cord.
•Be sure to pause the "POLARITY" switch in the center-off position before changing
polarity.
•Activate height adjustment (if available) during every following test.
•Maximum allowable test values under Normal Condition:
(Open Ground), Normal Polarity, Closed Neutral: 500 µA, but not 0 µA
(Open Ground), Reverse Polarity, Closed Neutral: 500 µA, but not 0 µA
(According to CAN/CSA - 22.2 No. 601.1 - M90, Sub-clause 19.3, Table IV)
•Maximum allowable test values under Single Fault Condition:
(Open Ground), Normal Polarity, Open Neutral: 1000 µA
(Open Ground), Reverse Polarity, Open Neutral: 1000 µA
(According to CAN/CSA - 22.2 No. 601.1 - M90, Sub-clause 19.3, Table IV)
•Switch off Incubator.
2.4 Patient leakage current from the skin temperature connection to earth
•Remove the test lead from the µ-Test 2000 and leave all other selections from the
previous test the same.
•Units with one or two skin temperature connections on the left side of Incubator
housing:
Short all pins of the two skin temperature connectors using a shorting plug
79 10 484. Plug the other end into the input jack "RL" of the µ-Test 2000.
•Units without ThermoMonitoring:
Short all pins of the skin temperature connector by using the
a) Skin Temperature Sensor Simulator 79 01 236 with the switch in "REXT"
position. Short the two yellow "REXT" outlets from the simulator and connect

"REXT" to the input jack "RA" of the Biotek 501 Pro.
or
b) Use Adapter 2M 20 736 and short a sensor connector as a test lead to the
safety tester. Plug the other end into the input jack "RA" of the Biotek 501 Pro.
•Rotate "MODE" knob to "LEAD TO GND" position.
•Rotate "LEAD" knob to "RL" position.
•Set up the µ-Test 2000 for the following tests by using the switches labeled
