1.0 METER FUNCTIONS & DISPLAY SYMBOLS
1.1 FUNCTIONS (Figure 1)
1. Display: Backlit 3999 Count LCD screen
2. SELECT Button: Press to switch between:
• DC voltage and AC voltage measurement functions
• Resistance, diode, and continuity test functions
• Frequency and Duty Cycle measurement functions
• DC current and AC current measurement functions
• Celsius temperature and Fahrenheit temperature measurement functions
Hold for about 2 seconds to enable or disable Bluetooth communication
3. RELATIVE Button: Press to enter or exit Relative mode. Hold for about
2 seconds to start or stop recording readings in the memory of the meter.
4. 10A Terminal: Red test lead input jack for current measurements.
5. COM Terminal: Black test lead input jack common to all measurements.
6. INPUT Terminal: Red test lead input jack for all measurements
except current measurements.
7. Rotary Switch: Turn to power the meter on and off and select the desired
measurement function. To save battery power, turn to the "OFF" position when
the meter is not in use. See "ROTARY SWITCH" section for function descriptions.
8. MAX/MIN Button: Press to enter or exit the Min/Max recording mode.
