Triplett Model 9310-A
Read the resistance on the display. Note the range annunciator ( Ω , k Ω , or M Ω ).
If it is desired to hold the reading, press the D-HOLD button so that the annun-
ciator is visible on the display.
If you wish to select the measurement range manually, press the RANGE button
repeatedly until the decimal point and the range annunciator agree with your ap-
plication.
If you have set the range manually, and the meter displays OL when the test leads
are connected to the circuit, you may have selected a range that is too low for the
resistance to be measured. In this case, press the RANGE button to select a higher
range, and attempt to measure the resistance again. If you are already set to the
highest range (
40M Ω ), the resistance exceeds the measurement capability of the
meter and can not be measured.
If you have set the range manually, and the displayed value is less than “400”, a
more accurate reading may be obtained by selecting a lower range. Use the RANGE
button to select the next lower range (you’ll need to press the button repeatedly to
get to the next lower range). Observe the reading on the LCD display. If the RANGE
is already on the lowest selection (i.e. 400
Ω
), no greater measurement resolu-
tion can be obtained.
Disconnect the test leads from the circuit under test and return the FUNCTION
Switch to the OFF position.
Note:
The REL button can be used to zero or “null” a reading in the resistance mode.
For example, the meter can be used to compare the resistance of many different
resistors, if one resistor is used as a “reference” resistor. If a resistor whose value
is exactly 100 Ohms is connected to the meter, it will read “100.0”. If the REL
button is pressed, the meter will “null” the “100.0” reading to “000.0”. If the
reference resistor is removed and other resistors connected, the difference in
value between the reference resistor and the resistor being tested will be dis-
played. For example, if a 113 Ohm resistor is connected, the meter will display
“013.0”….. the difference between the 100 Ohm resistor and the 113 Ohm resis-
tor. Similarly, if a 92 Ohm resistor is connected, the meter will display “-008.0”.
