Operation
Before taking any measurements, read the Safety Information Section. Always examine the instrument for damage, contamination, and defects. Examine the test leads for cracked or frayed insulation. If any abnormal conditions exist, do not attempt to make any measurements.
Manually Selecting a Range:
To manually select a range, press the [RANGE] button to hold the selected range. Subsequently pressing the [RANGE] button will select each range in sequence from the lowest to highest range. Hold the button for 2 seconds to return to the Autorange Mode.
Hold Button:
Press the (HOLD) button to toggle in and out of the Data Hold mode. In the Data Hold mode, the “HOLD” annunciator is displayed and the last reading is frozen on the display. Press the (HOLD) button again to exit and resume readings.
Mode Switch A:
Press this switch to toggle between DC and AC in the current measurements.
Mode Switch -4/»+:
If the function switch is set to +4/-»+ position, press this switch to toggle between the continuity/diode modes.
Voltage Measurements:
1. Connect the red test lead to the “VQ” jack and the black test lead to the “COM” jack.
2. Set the Function switch to the desired voltage type (V==: or V~) position.
3. Connect the test leads to the point of measurements and read the value from the display. The value indicated in the display window is the measured value of voltage with proper decimal point and annunciator indication. For DC, a (-) sign is displayed for negative polarity, positive polarity is implied.
Resistance Measurements:
1. Set the Function switch to the ‘(2” position.
2. Turn off power to the circuit under test. External voltage across the components causes invalid readings.
3. Connect the red test lead to the “VQ” jack and the black test lead to the “COM” jack.
4. Connect the test leads to the point of measurements and read the value from the display. The range will change automatically to the level that will display the input voltage with best resolution.
Testing Diodes:
1. Set the Function switch to ~#/-»+ position.
2. Turn off power to the circuit under test. External voltage across the components causes invalid readings.
3. To toggle between the continuity/diode modes, press Mode Switch.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V (typical for a silicon diode).
5. Reverse probes. If the diode is good, “OL” is displayed. If the diode is shorted, a value near OmV will be displayed.
6. If the diode is open, “OL” is displayed in both directions.
Current Measurements:
1. Set the Function switch to the desired current range (uA, mA or 10A) position.
2. To toggle between “DC” and “AC” mode, press Mode switch. The “DC” or “AC” annunciators is displayed in the upper left corner.

Safety & Warnings
Always inspect your meter, test leads, and accessories for any sign of damage or abnormality before every use. If any abnormal conditions exist, do not attempt to take any measurements. Do not expose the instrument to direct sunlight, extreme temperature, or moisture. Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material. To avoid electric shock, use caution when working with voltages above 40Vdc or 20Vac. Never exceed the maximum allowable input value of any function when taking a measurement. Refer to the specification for maximum inputs. Never touch exposed wiring, connections, or any live circuit when attempting to take measurements. When using the probes, keep your fingers behind the finger guards on the probes. Measuring voltage which exceeds the limits of the multimeter may damage the meter and expose the operator to a shock hazard. Always recognize the meter voltage limit as stated on the front of the meter.
