ELECTRICAL SPECIFICATIONS

• Voltage Level Indicators:
  • AC: 12V, 24V, 120V, 240V
  • DC: 1.5V, 9V, 12V, >17V
• DC Polarity Indicators: DC Positive, DC Negative, both illuminated indicates AC
• Hazardous Voltage Indicator:
  • Continuously on when voltage >25V AC or >25V DC
  • Blinking at ~2Hz when voltage >240V AC or >60V DC
• AC Frequency: 50Hz / 60Hz
• Input Protection: 250V AC/DC
• Maximum Measurable Voltage: 240V AC (240V AC Indicator) or 24V DC (>17V DC Indicator)
• Accuracy: Voltage level indicators typically illuminate fully at approx. 70% to 100% of indicated voltage, except for 12V DC (84% to 100%) and >17V DC (94% to 100% of 17V)
• Auto Power-OFF : After 2 minutes of inactivity Specifications subject to change.

WARNINGS
To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.

• Before each use verify tester operation by measuring a known voltage.
• Never use the tester on a circuit with voltages that exceed the category based rating of this tester.
• Do not use the tester during electrical storms or in wet weather.
• Do not use the tester or test leads if they appear to be damaged.
• Keep fingers behind the finger guards and away from the metal probe contacts when making measurements.
• Use caution when working with voltages above 25V AC RMS or 60V DC. Such voltages pose a shock hazard.
•  Always adhere to local and national safety codes. Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed.
• Tester is IP41 dust & water resistant. Following any contact with water, thoroughly dry tester prior to subsequent use.

CAUTION

•  DO NOT attempt to repair this tester. It contains no serviceable parts.
• DO NOT expose tester to extremes in temperature or high humidity.

OPERATING INSTRUCTIONS

• TESTING IN CAT III MEASUREMENT LOCATIONS
  Ensure the test lead shield is pressed firmly in place. Failure to use the CATIII shield increases arc-flash risk.

• TESTING IN CAT II MEASUREMENT LOCATIONS
  CAT III shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets. Take care not to lose the shields

OPERATING INSTRUCTIONS

• Press and hold the On/Off button 1 for approx. 1 second to turn the tester on or off. When on, the Power/Low Battery indicator 2 will be continuously illuminated. The tester will automatically power-OFF following 2 minutes of inactivity to conserve battery life.
• Apply test leads 6 to the system under test to measure voltage. The Voltage Level Indicators 3 will illuminate indicating the voltage present. When DC voltage is detected, the “+” or “–” polarity indicator 4 will illuminate, revealing the polarity. When AC voltage is detected, both polarity indicators will illuminate
  DO NOT attempt to measure AC voltages in excess of 240V AC, or DC voltages in excess of 25V DC under any circumstances. The hazardous voltage indicator will illuminate in the presence of voltage exceeding 25V AC or DC, with characteristics as detailed in the table below. HAZARDOUS VOLTAGE INDICATOR STATUS| AC VOLTAGE| DC VOLTAGE
  ---|---|---
  Solid on| >25V AC| >25V DC
  Blinking at approx. 2Hz| >240V AC| >60V DC

BATTERY REPLACEMENT

When the Power-ON / Low Battery indicator 2 blinks, the batteries must be replaced.

1. Remove screw 8 from battery compartment door 7 .
2. Remove and recycle spent batteries.
3. Install two new AAA batteries. Note proper polarity.
4. Replace battery door and fasten securely with screw.
   • To avoid risk of electric shock, disconnect leads from any voltage source before removing battery door.
   • To avoid risk of electric shock, do not operate tester while battery door is removed.

CLEANING

• Ensure tester is turned off and wipe with a clean, dry lint-free cloth.
• Do not use abrasive cleaners or solvents.

STORAGE

Remove the batteries when not in use for a prolonged period of time. Do not expose to high temperatures or humidity. After a period of storage in extreme conditions exceeding the limits mentioned in the General Specifications section, allow the tester to return to normal operating conditions before using.

DISPOSAL / RECYCLE

Do not place equipment and its accessories in the trash. Items must be properly disposed of in accordance with local regulations. Please see www.epa.gov or www.erecycle.org for additional information.
