Current measurements are different from other measurements made with a multimeter in that

current is measured in series.

The display rate of a digital multimeter is:

the number of time per second that the meter takes a measurement.

A 3 1/2-digit meter, can display three full digits ranging from

0 to 9, and one half digit which displays a 1 or is left blank For example 1,999

the largest allowable error that occurs under specific operating conditions is

accuracy

Measurement of electrical current, voltage using digital multimeter the indication is:

RMS values

Bryans Leak Tester

This type of leak tester is used for checking low-pressure pipelines as used on aircraft manometric instrument systems including engine pressure ratio systems.

• If the covers and blanks not remove from pitot probes and static ports before flight may cause Error in:

airspeed and altitude - sensing

On a static leak tester pressure is released by

a bleed valve in the tester

Checked AC circuit if it’s open or live AC circuit by using Multimeter when set to

AC volt.

A resistor that is placed in series with the meter movement is called

a multiplier resistor

An ammeter, its coil has relatively ………………………(low Resistance to prevent volt drop across it).

few turns of heavy wire

Some earlier cable constructions tended to exhibit ‘knuckling of conductors which could be severe enough to penetrate the insulation. This was induced by applying

excessive pull through forces

Continuity testing

to find a high resistance or open circuit carries out.

Any ohmmeter used for measuring insulation resistance must be used in association with a source of supply having an output voltage that is at least

equal to or higher than the working voltage.

Aircraft equipment which contains voltage sensitive devices will have CAUTION notices indicating that the equipment must not be subjected to:

• An insulation test under any circumstances

Ensure that the equipment or conductor to be tested is

de-energized before connecting the instrument.

Before using a bonding tester the 6 foot leads has the two prongs shorted together what would the indicator read?

Full scale right

The Moving Iron or Iron Vane Type Meter This type of movement is its cheapness and it may be used in

both AC and DC.

Continuity test carried out using

an Ohmmeter

DMMs display the ………….of these voltage waveforms or current.

The RMS value is the effective or equivalent DC value of the
