Press and hold the power button 1 for two seconds to power ON/OFF the tester. When the tester is powered ON and not connected to a circuit, the LCD 3 will display "" A and "Open Hot" B condition. NOTE: The tester will automatically power OFF after 3 minutes of inactivity to conserve battery life.
Prior to use, always verify tester operation by testing on a known live and correctly wired electrical outlet.
With the tester powered ON and inserted in the outlet, the Hazardous Voltage Indicator F will appear, and the red or green Indicator LED(s) 4 will illuminate. If the red indicator LED illuminates, unplug the tester to read voltage A and wiring fault B . The tester holds the information on the LCD and the Hold Mode indicator D will illuminate. During this time the LCD will blink. The LCD will reset once it is plugged into another circuit, or, if no voltage is detected, the LCD will blink during the time-out period prior to auto-power off.
If the tester indicates that the circuit is not wired correctly, consult a qualified electrician.
NOTE: Conditions NOT indicated include, but are not limited to, quality of ground, multiple hot wires, reversal of neutral and ground conductors, and combinations of defects other than dual open neutral and ground.
NOTE: All appliances or equipment on the circuit being tested should be unplugged to help reduce the possibility of erroneous readings.
*Expected voltage reading on LCD based on the indicated wiring condition.
NOTE: If the detected voltage is either low (30–85V AC) or high (135–150V AC), the red LED will illuminate. It is possible to have the red LED (indicating low or high voltage) and the green LED (indicating correct wiring) illuminated simultaneously.
NOTE: Prior to using this tester, check the GFCI device's user manual for information on how the specific device operates.
Power ON the tester 1 and insert the plug into the outlet of the circuit under test. On a properly wired circuit, the green Indicator LED 4, the Hazardous Voltage Indicator F and the Correct Wiring Indicator G will illuminate.
If the tester indicates that the circuit is not wired correctly, DO NOT attempt to initiate an electrical testing event. Consult a qualified electrician.
To initiate an electrical fault, press the GFCI button. The tester will create a 6mA to 9mA ground fault to trip the GFCI device. If successful, the display will toggle
A between the pre-test voltage and time to trip the breaker. If the circuit remains energized, or if "> sec" appears on the LCD, the device being tested may be miswired, may not be installed correctly, or may not be functioning correctly. Consult a qualified electrician.
When the Low Battery Indicator E illuminates, replace the batteries.
To avoid risk of electric shock, unplug from any voltage source before removing battery door.
To avoid risk of electric shock, do not operate tester while battery door is removed.
The RT250 is an electrical circuit tester that tests the wiring conditions at an electrical outlet, and inspects GFCI devices. The LCD displays the voltage, the wiring fault, and the GFCI trip time. It is designed for use with North American 120V electrical outlets.
Specifications subject to change.
To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.
Be sure tester is turned off and wipe with a clean, dry lint-free cloth. Do not use abrasive cleaners or solvents.
Remove the batteries when tester is 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.
