Operating Instructions
This section contains operating instructions for the Compliance West USA MegaPulse 968-B Metallic A
Tester.
•
In case of trouble, the test can be immediately terminated at any time by turning the rear-panel power
switch to the OFF position.
•
Before the test can commence, the unit must be armed by pressing the
CHARGE
Button. The test
will not begin until the
TRIGGER
Button is pushed.
•
Voltage is discharged by a resistor bank within the MegaPulse tester upon test completion.
Discharge progress is shown on the front panel meter.
Your tester is warranted for a period of one year upon shipment of the instrument to the original purchaser.
External Interlock
The external interlock is a two-position terminal block located on the rear panel. When the External Interlock
is open:
•
TRIGGER and CHARGE lights will be blinking.
•
The front keyboard will be disabled.
•
If the unit is connected to a computer with the TestMinder software, the interlock status
will be shown on the computer, condition that will also disable polarity changes, charge,
and trigger conditions.
When the Interlock is closed, it enables all normal operations of the MegaPulse features.
Front Keyboard and Voltage Knob Enable
If the MegaPulse 968-B Metallic A Tester has disabled the keyboard or Voltage Knob, it is possible to enable
them by using the next keyboard sequence:
1.
Turn OFF the MegaPulse P tester.
2.
Press and hold the
TRIGGER
and
NOR-REV
buttons
.
3.
Turn ON the MegaPulse tester.
4.
Wait until the display shows rESE.
5.
Release the TRIGGER and NOR-REV buttons.
Discharging Residual Voltage
Note that the Voltage meter may indicate that some residual voltage is present on the main storage capacitor,
even when the MegaPulse tester is first turned ON. This is due to inherent charging of the internal capacitors.
The following procedure will explain how to discharge a remaining voltage stored on the main internal
capacitor.
CAUTION
High voltage generated by the MegaPulse tester is exposed during this test. A risk of shock exists.
Exercise care when using the MegaPulse unit.
1.
Turn the rear-panel Power Switch OFF.
2.
Disconnect the high voltage cables from the outputs connector.
