6. Operating Instructions
The DT-17N features automatic identification for many ranges, simplifying operation. For specific functions, use the rotary switch and SELECT button.
6.1 Power On/Off and Backlight
- To turn on the multimeter, rotate the Function Selection Switch from OFF to any desired measurement function.
- To turn off, rotate the switch back to OFF.
- To activate the backlight, long press the HOLD key for approximately 3 seconds. The backlight will automatically turn off after about 15 seconds to conserve battery.
6.2 Automatic Identification Range
The DT-17N automatically identifies the measurement range for many functions, eliminating the need for manual adjustment. Simply select the general function (e.g., Voltage) and the meter will adapt.
6.3 Measuring Voltage (DC/AC)
- Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
- Rotate the Function Selection Switch to the 'V' position. The meter will automatically detect AC or DC voltage.
- Touch the test probes to the desired test points in the circuit.
- Read the voltage value on the LCD display.
6.4 Measuring Current (DC/AC)
Caution: Always connect the multimeter in series with the circuit when measuring current. Ensure the circuit is de-energized before connecting the meter.
- Connect the black test lead to the COM jack.
- For currents up to 600mA, connect the red test lead to the mA uA jack. For currents up to 10A, connect the red test lead to the 10A jack.
- Rotate the Function Selection Switch to the 'A' position (for current). Use the SELECT button to toggle between DC and AC current if needed.
- Break the circuit and connect the test probes in series with the load.
- Apply power to the circuit and read the current value on the LCD display.
6.5 Measuring Resistance
