Using the Features
All Models
• SELECT: Press momentarily to toggle between functions.
• : Press and hold until backlight illuminates. Press and hold again to turn off. The
backlight automatically turns off after approximately 30 seconds to extend battery life.
• RANGE: Press once to enter the manual ranging mode. The icon will disappear
from the display. Press repeatedly to step through the ranges. Press and hold to return to the
automatic ranging mode.
Note: When using MAX/MIN, HOLD, or Δ mode, pressing RANGE will cause the meter to exit
that mode.
• REL: Finds the difference between two measurements. While taking a measurement,
press REL to set the display to zero. The Δ icon will appear on the display. Take the second
measurement. The value on the display will be the difference between the two measurements.
Press again to exit this mode.
• Hz: Press and hold until the meter beeps to enable frequency measurement. The frequency
function can be used with the selector in any voltage or current setting. Use the V or A
settings for measuring the frequency of sinusoidal waveforms. Use the mV setting for
measuring the frequency of 3 volt or 5 volt logic level, square waveform signals.
The sensitivity of the frequency measurement function varies with the measurement range. To
automatically select a sensitivity level, measure the voltage or current first, and then press Hz.
If the reading becomes unstable or reads zero, press the RANGE button to select a different
sensitivity level.
The number of bar graph elements indicates the sensitivity selected:
• 1 element = 6 V, 6 A, 60 mA, or 600 μA
• 2 elements = 60 V, 10 A, 600 mA, or 6000 μA
• 3 elements = 600 V
• 4 elements = 1000 V
• HOLD : Press momentarily to hold the present value on the display. Press again to exit this
mode.
This feature does not affect the bar graph.
• EF: Set the meter to any current or voltage function. Press and hold until the meter beeps to
detect the electric field that surrounds current-carrying conductors. Signal strength is
displayed as a series of dashes on the display.
• Use the tester's built-in antenna (located along the top, near the LCD) for tracing live
circuits or locating a break in a wire.
• For more precision, such as distinguishing between current-carrying and ground wires,
connect a test lead to the ΩV input terminal and use it as a probe for direct contact
verification of AC voltage.
