MULTI-TESTER / BREAK OUT BOX PROCEDURES

BATTERY TESTER:

• Make sure all switches are in the “Off” or “Break” Position and connect both Test Handles to the Battery.
• Place the Battery Tester/Line Monitor switch to the Battery Tester position.
• Place the Up Hole/Down Hole Switch in the Up Hole position
• Place the Battery Full Load/Battery Depass Load switch to the Battery Depass position.
• Monitor the Voltage on the Analog Meter until the voltage is within specifications.
• Now place the Full Load/Depass Load switch to the Full Load position.
• Monitor the voltage on the Analog Voltmeter and make sure it passes the Loaded specifications.
• Place the Up Hole/Down Hole switch to the Down Hole position. This will test the resistance of the connectors; make sure that there is no big difference in voltage from Up Hole to Down Hole position.

LINE TESTER:

• Make sure all switches are in the “Off” or “Break” Position.
• Connect the Down Hole test handle of the Break Out Box to the top of a complete tool string.
• Place the Battery Tester/Line Monitor switch to the Line Monitor position.
• Rotate the Line Selector switch to the desired line that you wish to monitor. The voltage of the line selected will be displayed on the Analog Voltmeter.
• Test each line and verify that the voltage present is correct. This option could be used to check Battery 1, Battery 2, Battery Buss voltage and even shorted or open connections during assembly.

BREAK OUT BOX: (see Break Out Box here)

• Make sure all switches are in the “Off” or “Break” Position.
• The Multi-Tester can now be used as a standard Break Out Box with all the other options disabled.

TROUBLESHOOTING MODE:
The Multi-Tester can be used as a troubleshooting tool when you have a bad tool string. The following is just one example of how the tester could be used to help troubleshoot a tool that will not pass a Tap Test.

• Make sure all the switches are in the “Off” or “Break” position.
• Remove the interconnect connected to the pulser and replace it with the Multi-Tester.
• Place the switches of the Break Out box to the Make position.
• Place the Battery Tester/Line Monitor switch to the Line Monitor position.
• Using the Line Selector switch verify that all the battery voltages are displayed on the Analog Voltmeter.
• Battery Voltages are present and correct, then there is another problem.
• Rotate the Line Selector switch to Line 7; perform another tap test and verify that the Analog Voltmeter displays 5Vdc. If the reading is correct then the problem is either in the electronics or the pulser.
• Rotate the Line Selector switch to Line 6; perform another Tap Test and after the Transmit Delay Time has been reached in the electronics Line 7 should start pulsing from 0V to 5V.
• If there are no pulses, then place Line 6 switch in the “Break” position. This will isolate the pulse line from the pulser and the electronics to determine if either the problem is in the pulser or in the tool string.
• Using an external meter, connect it to line 1 and Line 6 on the Up Hole side of the Tester.
• Perform another Tap Test and after the Transmit Delay Time had expired the external meter should start pulsing from 0V to 5V. If there are no still no pulses then the problem is probably in the electronics if all the readings in the Line Test were good.
