LCD Annunciators

nS
Conductance Range Annunciator (nS):
Top range of the resistance function is the conductance range. Displays
conductance in nS (nanosiemens). 1000/nS converts to Mfl . (Example:
2 nS converts to 500BAO.) Use for measuring resistance above 32AAn .
Select n , open test leads, press RANGE button twice. (Refer to item 7
for manual range operation.)
. 1. Analog Bar Graph Display:
Analog representation of input. Composed of 31 segments which illuminate
starting from the left as the input increases. (See display inside front
cover.) A minus sign (INA ) is displayed for reverse-polarity inputs.
Updated 25 times per second.

Decimal Point/Range Indicator:
Decimal point position and the digits (3, 30, 300) under the decimal
point indicate the range in use.
Manual Range Annunciator:
Displayed in the Manual Range mode or if the selected function has only
one range. Absence of the indicator implies autorange mode in use. The
meter powers-up in autorange. In autorange, the meter automatically
selects the measurement range. Refer to item 7 for operation.

n
Low Battery Annunciator:
At least 40 hours of battery life remain when first displayed. Battery
voltage is tested each time the function switch is moved to a new
position.
Negative Polarity Annunciator:
Automatically indicates negative inputs.
o
t.
Overload Indication:
Indicates that the input is too large for the input circuitry. (The
location of the decimal point depends on the measurement range.)
® OF
Overflow Indication:
Indicates that the calculated difference in the Relative mode is too
large to display
(>3999
counts) and that the input is not overloaded.
q
)Beeper (not illustrated):
The beeper emits beeps, clicks, or a continuous tone. It is used for
audible indication in the diode test mode, when operating the push
buttons, and when a new reading is displayed in the Touch-Hold mode.
