Triplett 2030-C - Manual (Page 2)

MAKING MEASUREMENTS, GENERAL INFORMATION
To make a measurement, open the lid of the meter and rotate the rotary switch to the position appropri-
ate to the quantity to be measured. If appropriate, press the pushbuttons to further define the desired
type of measurement. The AutoRanging feature of the meter will automatically select the range which
will produce the most accurate reading. Alternately, the user may manually select the range by pressing
and releasing the RANGE button. Note the position of the decimal point, and the annunciator (like mV
or V) to determine the selected range. Note: The Capacitance (
) and Frequency (Hz) measurement
functions are Autorange only.
The selected range should be higher than the expected input value. For example, if a 120 Volt AC
household circuit is to be measured, set the meter to the 400 Volt AC range. If a 12 Volt car battery is to
be measured, set the meter to the 40 Volt DC range. If the level of the quantity being measured is
unknown, always set the meter to the highest appropriate range.
To reset the meter from Manual operation to AutoRange operation, press and hold the RANGE button
until the meter beeps and AutoRange operation commences (the AUTO annunciator will turn on).
NOTE: Carefully remove the test leads from their storage compartment on the meter and extend them
to their full length. Observing the proper polarity (red is positive and black is negative), and following all
applicable safety rules, connect the test leads to the circuit to be measured. Read the voltage on the
LCD display.
If the meter continuously overranges while attempting to measure voltage, immediately disconnect the
test leads from the circuit being measured. Reset the meter to an appropriate range and try making the
measurement again, or discontinue using the meter to perform the test. The quantity that you are trying
to measure may exceed the capability of this meter, and continued attempts at making a measurement
may result in damage to the meter or user injury.
When finished making measurements, carefully fold the test leads back into the storage compartment,
starting with the leads themselves, and finishing by capturing the tips of the probes with the flip cover
and folding it down into the compartment. Before closing the lid of the meter, verify that the test leads
are completely enclosed in the storage compartment, and set the rotary switch to the OFF position.
When the knob is set to OFF, it aligns with the “power slot” in the lid of the case, allowing the lid to be
closed. This feature guarantees that the meter is turned off when the lid is closed, thereby extending
the battery life.
HOLD
A reading appearing in the LCD can be held by pressing and releasing the HOLD button. The HOLD
annunciator
H will appear in the display when this feature is activated. This feature allows the user to
take a measurement for a few seconds, press the HOLD button, and “capture” the reading on the LCD.
The HOLD mode is released by pressing the HOLD button again, pressing a different button, or by
turning the rotary switch.
WARNING!!! DO NOT TURN ROTARY SWITCH IF AN INPUT IS APPLIED TO THE METER
AUTO POWER OFF
The 2030-C incorporates an Auto Power Off feature designed to lengthen the battery life. If the switch
and the buttons are undisturbed over a period of time, the meter will automatically “go to sleep”. Once
the meter has “gone to sleep”, a press of one of the buttons or turning the rotary switch will “wake it
up”. The time out interval for the 2030-C is approximately 30 minutes.
WARNING!!! DO NOT TURN ROTARY SWITCH IF AN INPUT IS APPLIED TO THE METER
AC and DC VOLTAGE MEASUREMENTS
WARNING!!! THE MAXIMUM INPUT VOLTAGE IS 600 VOLTS AC/DC

Follow the procedures outlined in the Safety Rules and General Information
Note: This meter is not intended to perform in-circuit testing of resistors.
1) Set the rotary switch to the OHMs mode (
Ω
).
If using the AutoRange feature, proceed to Step 2). If using the MANUAL range mode, refer to the
instructions given under MAKING MEASUREMENTS, GENERAL INFORMATION.
2) Connect the test leads to the circuit to be measured, observing the proper polarity of the leads (if
important in your application).
3) Read the displayed resistance on the LCD.
DIODE TEST
WARNING!!! REMOVE ALL POWER FROM THE CIRCUIT BEING TESTED. FOLLOW
APPROPRIATE PROCEDURES TO REMOVE CHARGE FROM ANY CAPACITORS IN THE CIRCUIT.
NEVER CONNECT THE TEST LEADS TO ANY SOURCE OF VOLTAGE
WHEN THE METER IS SET TO DIODE TEST.
Follow the procedures outlined in the Safety Rules and General Information
Note: This meter is not intended to perform in-circuit testing of diodes.
1) Set the rotary switch to DIODE (
Ω
).
Press the SELECT/REL
∆
button (
Ω
) while observing the annunciators on the LCD
display. Select the DIODE mode of operation.
2) Connect the test leads to the circuit to be measured, observing the proper polarity of the leads.
3) Read the diode voltage on the LCD.

2) Connect the test leads to the capacitor to be measured, observing the proper polarity of the
leads (if important in your application).
3) Read the displayed capacitance on the LCD.
NOTE 1: The response time of the capacitor measurement mode lengthens as the capacitance being
tested increases. On the highest range (100
µ
F), response time can be 10 seconds or longer.
NOTE 2: The 2030-C will not determine if a capacitor is “good” or “bad”...... it only measures the value
of the capacitor. A capacitor which measures OL may be Shorted or Leaky.
FREQUENCY AND DUTY CYCLE MEASUREMENT
WARNING!!! THE MAXIMUM INPUT VOLTAGE IS 600 VOLTS AC
Follow the procedures outlined in the Safety Rules and General Information
1) Set the rotary switch to Hz.

REL (RELATIVE) MODE
The 2030-C incorporates a useful REL Mode that works in the Capacitance and Voltage measuring
functions. It does not work in the OHMS, DIODE TEST, CONTINUITY, FREQ,
µ
A, or mA functions.
To “null out” the residual capacitance of the 40nF range (which can be as high as 150 digits), turn the
rotary switch to the CAP range, observe the LCD reading, and then press the SELECT/REL
∆
button.
The displayed reading should drop to 00.00nF. Proceed to measure capacitance as described previ-
ously.
Similarly, residual readings on the V AC and V DC ranges can be nulled out, or, for special testing
purposes, actual AC or DC voltage readings can be nulled to zero, and changes in the input quantity
observed as positive and negative deviations from zero.
