Z1884 Safety Notes—Front, Top, and Right Side
1. Safety ledge
Prevents objects from sliding off when the tester is tilted.
2. Emergency Manual Off (EMO) switch

pressing the Power Control switch on the operator control panel. Power is still present
on the line conditioner, AC power control, and unswitched user outlets.
3. Fixture receiver
Warning. Hazardous voltages may be present on fixture receiver during test.
• Do not remove fixture receiver covers while a program is running. Power may be
applied to the fixture receiver, consequently placing you at risk.
•
Keep fingers away from fixture receiver pins.
• Remove rings, watches, bracelets, or any loose or conductive apparel.
•
Observe proper ESD precautions.
4. Test jack panel
When the analog debug LED is on, and the High Voltage option is installed, high
voltage may be present on the E, F, and G test points.
The wrist strap receptacle grounds the antistatic wrist strap. Connect the wrist strap to
one of the receptacles on the tester and wear it at all times when you are working on the
system except when you are working on the AC power control or when you are
otherwise instructed.
5. Operator control panel
•
The Power Control switch turns power to the tester on and off. However, when the
Power Control switch is off, the unswitched outlets are still powered. See the
“Emergency Off Procedures” section for more detailed information.
• Pressing the Cancel switch stops test execution and returns to the start of the program.
