1.0 METER FUNCTIONS Meter type: Manual Functions: 8 Ranges: 28 Display Count: 1999 Test Lead Icons: on display indication of proper test lead input for easy to see proper test lead placement. Input impedance: 10 Meg Ohm AC Volt Ranges: 2V, 20V, 200V, 750V, best accuracy (0.8%+5) DC Volt Ranges: 200mV, 2V, 20V, 200V and 1000V, best accuracy (0.5%+5) AC Amps: 200µA, 2mA, 20mA, 200mA and 10A, best accuracy (1.0%+5) DC Amps: 200µA, 2mA, 20mA, 200mA and 10A, best accuracy (0.
CAUTION • Set the Function Switch to an appropriate position before starting measurement. • Firmly insert the test leads. • Disconnect the test leads from the instrument for current measurement. • Do not expose the instrument to the direct sun, high temperature and humidity or dewfall. • Be sure to power off the instrument after use. When the instrument will not be in use for a long period, place it in storage after removing the batteries.
2.2 OPERATING INSTRUCTIONS 1. Set the function/range switch to the proper position before making a measurement. When the voltage is not known, it MUST be determined that the capacity of the selected range will handle the amount of voltage in the circuit (see #3 under “For Your Safety”). 2. Avoid placing the meter in areas where vibration, dust or dirt are present. Do not store the meter in excessively hot, humid or damp places.
4.4 DC AMPS A Never attempt an in-circuit current measurement where the open circuit voltage between terminals and ground is greater than 60V DC. If the fuse burns out during measurement, the Meter may be damaged or personal injury may occur. Use proper terminals, function, and range for the measurement. When the test leads are connected to the Amp terminals, DO NOT connect them in parallel across any circuit.
.0 BATTERY REPLACEMENT To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator appears 1. Disconnect the connection between the test leads and the circuit under test, and remove the test leads from the input terminals of the meter. 2. Turn the Meter power off. 3. Remove the rubber boot from the meter. 4. Remove the 3 screws from the case, and separate the case top from the case bottom. 5.
