(conDnuity test). Under temperature ranges, press SELECT key to choose Degrees
Celsius or Degrees Fahrenheit. Under ACV ranges, press SELECT key to switch
between Frequency or Duty Cycle measurement.
2) When there is no measurement in 15 minutes, the meter will automaDcally power
off and enter sleep mode. One minute before sleep mode, the buzzer will beep for 5
Dmes to remind user. Press any bu]on or turn the rotary switch will exit the sleep
mode.
3) Press SELECT key to acDve the meter from the sleep mode or hold the SELECT key
down when turn on the meter to cancel auto power off funcDon.
4) TORCH FUNCTION Key: Press TORCH FUNCTION key for more than 2 seconds to turn
on the torch. Press it for more than 2 seconds once again to turn off the torch.
RANGE/REL Key
1) Auto range is the default when you turn on the meter, and the meter displays
"AUTO" symbol. Press RANGE to enter manual range mode. Press RANGE to switch
between the ranges available for the selected funcDon. Hold the RANGE bu]on
down for more than 2 seconds to return to auto ranging,
2) Under capacitance measurement, press REL key to enter relaDve value test mode.
The display is zeroed, and △ symbol appears. Press REL key again to exit relaDve
value test mode.
HOLD/ Light Key
1) HOLD Key : Press HOLD key to enter HOLD mode. The current value will be hold, and
symbol "
