5. Control Buttons
a) Hz / % Button (fig. p.2 #2)
This button allows you to choose between frequency and the duty cycle in a frequency range.
Press the HZ/% button to measure the frequency or the duty cycle while measuring voltage or current. For the
voltage/current requirements and frequency range, see the following table (for reference only):
Range (AC/DC)
4V
40V, 400V
1000V/750V
400mA
10A
Press the HZ/% button again to return to regular voltage or current measurement.
b) Range Button (fig. p.2 #3)
When the meter is switched on, it automatically goes into auto ranging ("AUTO" indication on the display). This
automatically selects the best range for the measurements being made and is generally the best mode for most
measurements. For measurements situations requiring a manually selected range, perform the following steps:
1. Press the RANGE button; the "AUTO" indication on the display will disappear.
2. Press the RANGE button repeatedly to skip through the available ranges until the required one is selected.
3. To return to auto ranging, press and hold the RANGE button for more than 2 seconds.
