1. Introduction
The Triplett Model 1401 multimeter is a 6000 count, handheld digital
multimeter with auto-ranging capability, AC RMS measurement, automatic
power off and a backlit LCD display. Using a Large Scale Integration (LSI)
integrated circuit, the multimeter is designed for stability and accuracy. The
resilient outer molded cover provides additional protection from the occa-
sional fall, and the threaded probe tips and screw on insulated clips provide
for secure, hands-off measurements. The meter can measure AC and DC
voltage, AC and DC current, resistance, capacitance, frequency/duty cycle,
temperature, and forward diode voltage drop. It can also perform an audible
continuity test, non-contact AC voltage detection, and test both 1.5V and 9V
batteries.
2. Product Features
1) Test lead holder.
2) CDS sensor for automatic backlight brightness control.
3) NCV Detection area (top of DMM case).
4) NCV Detection voltage detected indicator (red LED).
5) NCV Detection mode activated indicator (green LED)
6) LCD display with (Low Battery), NCV, DH (Hold) and measurement
unit annunciators.
7) SELECT button: With the rotary switch on the “ “ range, press
this button to select resistance, diode, continuity or capacitance tests.
With the switch on either voltage or current selections, this switches
between DC and AC settings. If the temperature °C/°F is selected, it
switches between Centigrade or Fahrenheit. If the SELECT button is
held down while the meter is turned on, the “Auto Power Off ” function will
be disabled.
8) RANGE button: Press and release the “RANGE” button to enter manual
range mode. Additional presses cause the unit to change the
measurement range of the measurement function selected. Press and
holding the button for more than 2 seconds causes the meter to toggle
back to auto-ranging mode.
9) DISPLAY HOLD Button: Press the “HOLD” key to lock the present value
on the display. The “DH” sign will appear on the display while the hold
function is active. Press it again to exit and resume normal display
updating.
10) REL button: Press this button for the meter to enter relative
measurement mode. “REL” is displayed on the LCD and the present
reading becomes the reference value. In this mode, the displayed value
is the difference between any subsequent measurement and the
reference value: Relative measurement = measurement
value-Reference value.
11) Hz/% button: On “ACV/ACA” or “Hz” range, pressing the “Hz/%” key,
switches between Frequency or Duty Cycle measurements.
12) Rotary Switch: Use this switch to select test functions and ranges.
13) COM: COM and Temperature “-” Input Jack.
14) 10A: 10A Input Jack, fused at 10A., 500V
15) VΩmA: V/mA/BATT/ and Temperature “+” Input Jack, fused at
800mA, 500V
16) Meter case
17) Protective molded cover
3. Safety Information
3-1 The meter is designed according to IEC-1010 concerning electronic
measuring instruments with an over-voltage category level of 600V
(CAT III) and pollution level 2. DO NOT USE THIS METER FOR CAT
IV APPLICATIONS.
3-2 Follow all safety and operating instructions to ensure that the meter is
used safely and is kept in good operating condition.
3-3 Safety symbols:
Important safety information, refer to the operating manual.
Dangerous voltage may be present.
Double insulation (protection Class II)
4. Cautions and Warnings
4-1 To maintain product safety, use the provided test leads. Damaged test
leads should be replaced with the same model or test leads with the
same electrical specications.
4-2 Do not use with the battery cover removed.
4-3 Always set the rotary switch to the correct position for measurement.
4-4 Do not exceed the input limits.
4-5 Do not change the rotary switch setting when the leads are connected to
an energized circuit.
4-6 Use caution when measuring voltages higher than 60V DC or 30V AC.
4-7 Replace fuse with fuse of the same rating.
4-8 To conserve battery life, always turn the meter off when measurements
are completed.
