Accuracies are given at ambient conditions of 18 ... 28 °C, 65 ... 83 °F. *The temperature is

the difference between the temperature of the operating conditions and the current ambient

temperature.

Example:

If current ambient temperature is greater than the temperature of the operating conditions

(50 °C / 122 °F (current ambient temperature)) - (40 °C / 104 °F (operating temperature)) =

10°C / 50°F

If the current ambient temperature less than the temperature of the operating conditions

(0 °C / 32 °F (operating temperature)) - (-5 °C / °F (current ambient temperature)) =

5 °C / 41 °F

5 Operating Procedures

5.1 SMART Measurement

•Select the SMART measurement option with the rotary switch.

•Connect the test leads as required.

•AC current, AC voltage, DC voltage, resistance or continuity will be measured

automatically.

•When measuring AC current, the meter can simultaneously display the measurement

results for DCV or ACV, for example.

5.2 A-HOLD

•Press the A-HOLD button to pause the measurement on screen.

•Press the button again to resume measurement.

5.3 Auto Power-Off

•The meter shuts down automatically after 15min of inactivity,

•Press the A-HOLD button to wake the meter up.

AUTO

MIN

5.4 DC Voltage

•Select the DC voltage measurement option ( ) with the rotary switch.

•Connect the test leads as required to begin measurement.

CAUTION

Use extra caution when measuring high voltages to avoid electric shock or damage.

WARNING

Do not attempt to measure voltages above 600V DC

to prevent injury or damage to the meter.

5.5 AC Voltage

•Select the AC voltage measurement option ( ) with the rotary switch.

•Connect the test leads as required to begin measurement.

CAUTION

Use extra caution when measuring high voltages to avoid electric shock or damage.

WARNING

Do not attempt to measure voltages above 600V DC

to prevent injury or damage to the meter.

5.6 AC Current

•Select the AC voltage measurement option ( ) with the rotary switch.

•Insert only one conductor inside the current clap to begin measuring (Multiple

conductors with different current directions will cancel the measurement out).

5.7 Resistance

•Turn off all power and discharge the capacitors of the circuit to be tested.

•Select the resistance measurement option (Ω) with the rotary switch.

•Connect the test leads as required to begin measurement.

•Measuring tips:

oSometimes the resistor value and measured resistance differ. This is due to

the meter’s output test current going through all possible paths between

leads.

oFor low resistance measurements, shorten the test leads and record the

resistance displayed. Then connect to the circuit and subtract the recorded

resistance from the measured value for the most accurate results.

oWhen the leads are disconnected or the measurement is out of range, “OL”

will be shown on the display.

WARNING

To avoid injury or damage to the meter, make sure to turn off

all power and discharge all capacitors before measuring resistance.

5.8 Continuity

•Turn off all power and discharge the capacitors of the circuit to be tested.

•Select the resistance measurement option ( ) with the rotary switch.

•Connect the test leads as required to begin measurement. If the resistance is less than

40Ω, the buzzer will sound.

WARNING

To avoid injury or damage to the meter, make sure to turn off

all power and discharge all capacitors before measuring resistance.

5.9 Frequency/Duty Cycle

•Select the resistance measurement option (Hz%) with the rotary switch.

•Connect the test leads as required to begin measurement.

6 Maintenance

6.1 Cleaning

Use a damp cloth and a small amount of detergent to clean the meter regularly. Do not use

abrasives or chemical solvents. Dirty or wet input jacks can affect readings.

Cleaning the input jacks:

•Shut meter down and remove the test leads.

•Wipe any debris off the input jacks.

•Clean the inside of the input jacks with a cotton swab and an alcohol cleaner or lubricant

(eg.: WD-40).

•Use a clean swab for each jack to avoid cross contamination.

6.2 Battery Replacement

WARNING

Remove the test leads from before opening the

battery cover to avoid damage or personal injury.

To avoid false readings, damage to the meter or personal injury, replace the batteries when the

battery low icon is displayed.

To replace the batteries:

•Shut the meter down and remove all test leads.

•Unscrew the battery cover and remove the used batteries.

•Replace the batteries (AAA 1.5V, Alkaline)

•Reinstall the battery cover and tighten the screws.
