7. Operating Instructions

7-1 Before Operation

7-1-1 Check battery. If the battery voltage is low, the symbol will appear

on the LCD display. Replace by removing the (2) screws in the rear

panel and lifting the battery cover up.

7-1-2 The near the input jacks warns of limitations in the input voltage

and current. DO NOT EXCEED THESE LIMITS.

7-1-3 The rotary switch should be positioned to the proper function and

measurement range BEFORE connecting the test leads to the circuit.

7-2 Measuring DC Voltage

7-2-1 Connect the black test lead to COM jack and red lead to VΩmA jack.

7-2-2 Set the rotary switch to the desired “V ” range position.

7-2-3 Observing polarity, connect test leads across the circuit component(s)

under measurement and read the voltage from the LCD.

NOTE:

1. When the quantity to be measured is unknown, set the rotary switch to its

highest DC voltage range before connecting the test leads to the circuit.

2. When only “1” or “-1” is displayed, it indicates “over range”. Either select

a higher measurement range or do not continue to measure.

3. Although the meter may measure voltages higher than 600V, it may be

damaged or pose a shock hazard or other injury to the user.

4. Use caution when measuring high voltages (>60V DC or >30V AC).

7-3 Measuring AC Voltage

7-3-1 Connect the black test lead to COM jack and red lead to VΩmA jack.

7-3-2 Set the rotary switch to the desired “V ” range position.

7-3-3 Observing polarity, connect test leads across the circuit component(s)

under measurement and read the voltage from the LCD.

NOTE:

1. When the quantity to be measured is unknown, set the rotary switch to its

highest AC voltage range before connecting the test leads to the circuit.

2. When only “1” or “-1” is displayed, it indicates “over range”. Either select

a higher measurement range or do not continue to measure.

3. Although the meter may measure voltages higher than 600V, it may

be damaged or pose a shock hazard or other injury to the user.

4. Use caution when measuring high voltages (>60V DC or >30V AC).

7-4 Measuring DC Current

7-4-1 Connect the black test lead to COM jack and red lead to the VΩmA

jack for a maximum 800mA current. For a maximum 10A current,

move the red lead to the 10A jack.

7-4-2 Set the rotary switch to the desired “A ” range position. You can

press the RANGE button to switch between measurement ranges

manually, or leave the meter in “Auto” range mode.

7-4-3 Observing polarity, connect test leads in series with the load under

measurement.

7-4-4 Read current from the LCD.

NOTE:

1. When the quantity to be measured is unknown, be sure that the meter

is in “Autorange” mode and consider whether to use the 800mA or 10A

input jack before connecting test leads to the circuit.

2. When only “1” or “-1” is displayed, it indicates “over range”. Either select

a higher measurement range or do not continue to measure.

3. Current above 800mA on the VΩmA jack will blow the fuse. The 10A jack

fused at 10A. Do not apply more than 10A and do not apply 10A for

longer than 10 seconds. Allow a 15 minute cooldown.

4. If fuse blows, remove meter from circuit under test. Replace fuse by

removing the rear cover (2 screws) to access fuse.
