Do you want a premium and durable automotive multimeter? Here is the Fluke 88V automotive multimeter. Fluke is one of the most sought after and premium multimeter manufacturers. It manufacturers premium multimeters for many applications. Fluke 88V is a dedicated multimeter for working with automobiles and electric vehicles. The specific hardware of Fluke 88V makes it specialized for measuring the electrical circuit and equipment of automobiles. This multimeter has all the bells and whistles which are required while dealing with the automobile wiring and circuit.

Unlike other commonly used multimeters, this Fluke 88 is can perform a variety of tests of delicate and sensitive electrical components of engine, sensors and circuitry. The other excited and some exclusive features of Fluke 88 are given as:

Features

Exclusiveness

This multimeter is exclusive. There is a Fluke 88 is designed especially for the automotive. Although it does support some DIY tests and measurement but is has many exclusive tests. The exclusive tests are performed to check the working of different sensors, ignition coils and other circuitry of automobiles. These exclusive tests include Leakage Test, Duty Cycle Measurement, BP and MAP Sensor Test, Measurement of Internal Resistance of Ignition Coil, Measurement of the Pulse width of Port Fuel Injector, Ripple Voltage Test on an Alternator, Typical Oxygen Sensor Voltage Test, Measurement of Starter Circuit Voltage Drop and Throttle Position Sensor Voltage Test.

AutoHOLD

This feature allows the Fluke 88 Automotive Multimeter to auto-hold the reading for viewing. When the feature is turned on, the multimeter will hold the stable reading of every measurement. This feature can be toggled off and on with the dedicated button labelled as “AutoHOLD”.

Relative Mode

Relative Mode is a special feature for relative readings. Pressing the dedicated button set the current reading as a reference for future readings. If the current reading is 5A, the multimeter will turn it to 0 as the reference and will show the difference of future reading with 5A. This feature is useful when a person is intended to measure check whether the automobile battery is charging or not.

HiRes Mode

This mode allows a user to view the reading in a higher resolution. Pressing the button enables the HiRes mode which allows the device to display the reading at 10 times resolution. HiRes allows user to view the display and readings. This mode, however, is not available when measuring temperature, capacitance, frequency counter, temperature and min/max mode.

Min/Max Mode

This mode allows the Fluke 88 automotive multimeter to store the minimum and maximum readings of a session. When the mode is active, the multimeter will keep the record of minimum and maximum readings. Upon hitting any values which is either greater or less than the already stored minimum and maximum value, the multimeter will beep and update the value to a new minimum or maximum.

Input Alert Feature

Alert is a trademark feature of Fluke multimeter. When a test lead is connected to the mA/µA terminal but the user tries to measure voltage, continuity, resistance or capacitance, the multimeter will make a sound and display a “LEAD” error message. Hence the error message will stop the user from accidentally measuring the data with wrong connected leads.
