Button
Model HD160C has Digi-Glo TM backlighting, one of the best
backlights available in the industry. This button turns the
backlight on and off. To conserve battery life, backlight will
automatically turn off after approximately 60 seconds.
AC DC Mode Each press alternately selects the AC or DC mode for the
current function. The selected mode appears on the display
above the button.
RANGE
Locks the currently displayed range. Each subsequent push
of the button moves to a higher range. From highest range,
the meter returns to the lowest range. The meter functions
in the 4000 count mode when range is locked.
HOLD
Freezes the reading present on the LCD at the moment
the button is pressed. To use this button feature set up the
meter for the type of measurement and range desired.
Connect the test leads to the circuit/component to be
measured, then press Hold. The LCD reading will freeze and
display “HOLD.” You may now remove the test leads and
the reading will not change until you press Hold again.
REL
(Relative Measurements)
The Relative mode displays the difference between the
actual reading and a reference value. It may be used with
any function or range; however, the range must be set
manually. To make a relative measurement first establish
a reference value by measuring a value and then pressing
the REL button after the reading has stabilized. This stores
the measured value as the reference and sets the display
to zero. The meter subtracts the reference value from
subsequent measurements and displays this difference as
the relative value. Measurement values greater than the
reference value will be positive and values less than the
reference value will be negative. To exit the Relative Mode,
Press and hold the REL button for 2 seconds. Select the
proper Range using the RANGE button before enabling the
REL feature. This function will not autorange.
