3 Resistance Calibration
Note: Review the entire document before starting the calibration process.
3.1 Review the Performance Requirements in Table 5-1.
Note: Whenever the test requirement is not met, verify the results of each test and take corrective
action before proceeding.
3.2 Turn on the UUC by pressing the power button. The unit will complete a self-test
indicated by flashing each of the 4 voltage lights. Once the self-test is completed the
LED corresponding to the set voltage will flash.
Note: The UUC cannot be connected to the decade box while the self-test is running.
Warning: Touching the metal end of the UUC or of the red lead attached to it while it is on may
result in a mild electric shock.
3.3 Connect a red and a black lead to the LPD and the corresponding terminals of the RS-
201 decade box as shown below.
Note: The UUC cannot be connected to the multimeter during the resistance calibration.

Management Procedure 2559 Rev A Page 4of 7
3.4 Set the UUC to 9V and adjust the decade box to 90 kΩ.
3.4.1 If the UUC is constantly alarming as indicated by flashing the remaining 3 voltage
LEDS, increase the resistance on the RS-201, 100 Ωat a time, until the UUC stops
alarming or alarms intermittently. Record the last resistance value that the unit alarmed
constantly on. Record this value as kΩ. For example 89 kΩand 700 Ωwould be
recorded as 89.7 kΩ.
3.4.2 If the UUC is not alarming or is alarming intermittently decrease the resistance value
until the UUC starts alarming constantly. Record this resistance value.
3.4.3 Set the UUC to 67.5V, 80 kΩand adjust the decade box to 80 kΩ. Repeat steps 3.4.1 and
3.4.2.

Management Procedure 2559 Rev A Page 5of 7
3.5 Set the UUC to 67.5V, 90 kΩand adjust the decade box to 90 kΩ. Repeat steps 3.4.1 and
3.4.2.
3.6 Set the UUC to 90V and adjust the decade box to 400 kΩ. Repeat steps 3.4.1 and 3.4.2
but increase the resistance on the RS-201 1 kΩat a time
4 DC Voltage Calibration*
* optional calibration requiring the use of a calibrated multimeter.
4.1 Review the Performance Requirements in Table 5-1.
Note: Whenever the test requirement is not met, verify the results of each test and take corrective
action before proceeding.
4.1.1 Set-up the UUC as described in sections 3.2 and 3.3.
4.1.2 Turn on the multimeter and set it to DC Volts and auto-ranging.
4.1.3 Connect the positive and negative leads from the multimeter to the corresponding
terminals of the RS-201 decade box.
4.1.4 Set the UUC to 9V and adjust the decade box to 90 kΩ. Record the voltage displayed on
the multimeter to 2 decimal points (xx.xx).
4.1.5 Set the UUC to 67.5V, 80 kΩand adjust the decade box to 80 kΩ. Record the voltage
displayed on the multimeter.

4.1.6 Set the UUC to 67.5V, 90 kΩand adjust the decade box to 90 kΩ. Record the voltage
displayed on the multimeter.
4.1.7 Set the UUC to 90V and adjust the decade box to 400 kΩ. Record the voltage displayed
on the multimeter.
