Pushbuttons

Mode Button
The Mode Button is used to select Ohms/Diode/Continuity, DC/AC Current and Voltage,
Degrees F/C in the appropriate rotary switch settings.
1. In Current measurement function, pressing the Mode button will select the AC range
from the default DC range.
2. In Voltage/Frequency measurement function, pressing the Mode button once will
select the AC range from the default DC range. If the button is pressed for 3 seconds,
the meter will enter Frequency measurement function.
3. In Resistance/Diode/Continuity function, pressing the Mode button will change from
default Resistance function to Diode test and then Continuity test function.
4. In Temperature measurement function, pressing the Mode button will change from
default °C to °F units.
Peak Hold Button
The Peak Data Hold function records the maximum and minimum readings for current
and voltage on the display.
1. Press the Peak Hold button once to record the peak maximum value. The meter
beeps and indicator "P MAX" appears on the display.
2. Press the Peak Hold button again to record the peak minimum value. The meter
beeps and indicator "P MIN" appears on left-upper corner of the display.
