Minipa ET-2907 - Frequency (Hz) Measurements

73
When calculating the power dissipated in a circuit component, it is
critical that the DC value is factored into the equation V
RMS
x I
RMS
,
where V
RMS
is AC + DC total RMS.
Another useful feature of this Meter is AC DC dual display mode. AC
voltages riding on power supplies can cause problems with electronic
circuits. If the Meter is set to DC Volts mode, the display shows the DC
component of 6.0000V. However, the AC component may be missed. It
is recommended that you set the meter to AC DC dual display mode
by pressing the menukey 4 twice. The primary display shows the 1.2000
V AC voltage and the secondary display shows the 6.000V DC voltage.
That is, AC DC mode allows you to simultaneously make AC and DC
measurements without changing the meter settings.
5.2 Frequency (Hz) Measurements
The meter autoranges to one of six frequency ranges :
50.000Hz, 500.00Hz, 5.0000kHz, 50.000kHz, 500.0kHz and
5.0000 MHz.
The meter beeps to indicate when a particular pushbutton is not allowed
when measuring frequency. The 1ms Peak button cannot be used.
