Sealey TA320 - Manual (Page 23)

AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into
AutoRanging. This automatically selects the best range for the
measurements being made and is generally the best mode for most
measurements. For measurement situations requiring that a range
be manually selected, perform the following:
1. Press the RANGE key. The “AUTO” display indicator will turn off.
2. Press the RANGE key to step through the available ranges until
you select the range you want.
3. To exit the Manual Ranging mode and return to Autoranging,
press EXIT
Note: Manual ranging does not apply for the Temperature functions.
MAX/MIN
1. Press the MAX/MIN key to activate the MAX/MIN recording mode.
The display icon "MAX" will appear. The meter left auxiliary
display will display and hold the maximum reading and will update
only when a new “max” occurs. The display icon "MIN" will appear.
The right auxiliary display meter will display and hold the
minimum reading and will update only when a new “min” occurs.
2.To exit MAX/MIN mode press EXIT
RELATIVE MODE
The relative measurement feature allows you to make
measurements relative to a stored reference value. A reference
voltage, current, etc. can be stored and measurements made in
comparison to that value. The displayed value is the difference
between the reference value and the measured value. Note:
Relative mode does not operate in the 4-20mA function.
1. Perform the measurement as described in the operating
instructions.
2. Press the REL button to store the reading in the display and the
"REL" indicator will appear on the display.
