ZERo (Relative) Measurements (ACDC-3400 IND only)
The Relative mode displays the difference between the actual reading and a reference
value. It may be used with any function or range. To make a relative measurement first
establish a reference value by measuring a value and then pressing the 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 button for 2 seconds.
This feature should be used to set DC zero for DC amps.
HoLD button
Data hold freezes the reading present on the LCD at the moment the button is pressed.
To use this menu 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 push button. 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.
RANgE button
Allows the user to select the range of a function that does not show 'RANGE' on the
LCD.
backlight Push button
Turns the back light On or OFF.
Auto Power off (APo)
This meter will automatically turn the power off after 30 minutes. To disable the APO,
set the meter to off position, press and hold the (RANGE) or (MAX/MIN) button while
turning the rotary knob to the desired range position. Release the button when LCD
displays normally. Note "APO" annunciator is missing from the LCD.
