TPI 173A Autoranging DMM with boot, test leads, battery and manual

173A Autoranging DMM with boot, test leads, battery and manual by Test Products International

LCD Display
4000 count with 42 segment bar graph.

REC (Record Mode)
Store minimum and maximum readings over a measurement period.

RANGE
Manually select the appropriate range

AC/DC
Manually select AC or DC measurement function.

(Continuity Buzzer and Diode Test)
Toggle between continuity buzzer or diode test on Ohm function.

High Resolution DCmV Range
Additional 40 millivolt range with 0.01mV resolution for improved accuracy when performing low voltage measurements.

ACV (AC Volts)
Measure the voltage of ABS wheel sensors.

DCV (DC Volts)
Measure the voltage of circuits and sensors.

Hz/Duty (Duty Cycle)
Measure in percent the "ON" time of sensors or other devices.

REL (Relative Mode)
Factor out lead resistance for improved low ohm measurements or compare readings to a known standard. Can also be used for differential measurements.

HOLD
Lock the reading on the display for hard to read locations for future reference.

Ω (Ohms, Resistance)
Measure the resistance of spark plug wires, coils, sensors, and continuity of wiring.

AC/DC Current Functions (Amps)
Measure the parasitic draw from the battery with ignition off.

Hz (Frequency)
Measure the frequency of sensors and signals.

CAP (Capacitance)
Measure the capacitance of condensers or capacitors found in today’s hybrid automobiles.

Built in Tilt Stand
The tilt stand is built into the instrument housing.

Quickly Test Condition of Internal Fuses
You can determine the status of the internal fuses before you open the battery/fuse compartment. Simply set the instrument to the diode test function, plug the black test lead into the "VO2" input jack and touch the prod end of the black lead to the metal inside the "A" or "UAmA" input jack. If the meter reads "OL", the fuse is blown. If there is a reading on the LCD besides "OL", the fuse is good.

Separate Fuse/Battery Compartment
Easily replace fuses and batteries in this separate compartment. Fuses are clearly labeled with preplacement part number.

Features:

• REC Records Min/Max readings during specified measurement intervals.
• RANGE Allows the user to manually range the 173A instead of autoranging.
• HOLD Holds the reading on the display for easy viewing.
• REL Displays the value as a difference to a reference value.
• AUTO OFF Preserves battery life.
