In this mode, the unit will measure up to 50mADC or 20VDC. 
1. 

Turn the meter ON. 

2. 

“MEASURE” will appear in the display. 

3. 

Press and Hold the MODE button for

 

1 second

 

to select mA or % or mV 

4. 

Connect the Calibration Cable to the meter. 

5. 

Connect the Calibration Cable to the device or circuit under test. 

6. 

Read the measurement on the LCD display. 

In this mode, the unit can source current up to 24mADC at 1000 ohms or voltage up to 20.00V. 

The current or voltage can be output either manually or stepped from memory as described 
earlier. 
1. 

Turn the meter ON 

2.

3. 

Press and Hold the MODE button for

 

1 second to select mA or % or mV 

4. 

Momentarily press the “I/O” button to select SOURCE. 

5.

7. 

Connect the Calibration Cable to the device or circuit under test 

8. Use 

the 

arrow 

buttons to set the desired output value in the lower display. The upper 

display indicates the actual current or voltage value being sourced. If the upper display does 
not match the set value, either the batteries need to be replaced or the load impedance is 
beyond the specified range.
