BATTERY INSTALLATION BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. Turn power off and disconnect the test leads from the meter. 2. Open the rear battery cover by removing two screws (B) using a Phillips head screwdriver.
REPLACING THE FUSES WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the fuse cover. 1. Disconnect the test leads from the meter. 2. Remove the battery cover (two “B” screws) and the battery. 3.
OPERATING INSTRUCTIONS WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. NOTES: 1. ALWAYS turn the Function switch to the OFF position when the meter is not in use. 2.
AC VOLTAGE (FREQUENCY, DUTY CYCLE) MEASUREMENTS WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it.
DC CURRENT MEASUREMENTS CAUTION: Do not make 20A current measurements for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative COM jack. 2.
AC CURRENT (FREQUENCY, DUTY CYCLE) MEASUREMENTS CAUTION: Do not make 20A current measurements for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative COM jack.
RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. 1. Set the function switch to the ΩCAP position. 2.
DIODE TEST 1. Set the function switch to the Ω CAP position. 2. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. 3. Press the MODE button to indicate on the display.
CAPACITANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remove the batteries and unplug the line cords. 1. Set the rotary function switch to the Ω CAP position.
FREQUENCY SENSITIVITY (ELECTRICAL) The frequency sensitivity is range dependent when the Hz function is selected while in the voltage or current measuring mode. Below are typical sensitivities for the “electrical” measurement modes. Range Sensitivity Frequency ( DC/AC ) bandwidth ≥1.5V rms 5Hz~10kHz ≥10V rms 40V, 400V...
RELATIVE MODE The relative measurement feature allows you to make measurements relative to a stored zero reference value. A reference voltage, current, etc. can be stored and measurements made in comparison to that value. The displayed value is the difference between the reference value and the measured value.
MAINTENANCE WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse covers. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers are in place and fastened securely.
REPLACING THE BATTERY WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery door. 1. When the battery become exhausted or drops below the operating voltage, the low battery icon will appear in the lower left of the LCD display.
TROUBLESHOOTING There may be times when your meter does not operate properly. Should that happen, please follow the following steps: 1. Always read all the instructions in this manual before use. 2. If You Do Not Understand How the Meter Works, purchase the instructional book “Multitesters and Their Use for Electrical Testing”...
