Test Equipment Flashcards
A resistance reading of OL or Infinity indicates
a resistance higher than the meter is capable of reading
A resistance reading of 2.4M ohms could be expressed as
2 400 000 ohms
The term impedance, as related to test equipment, indicates
the amount the test equipment will load the equipment
the first step in operating a digital multimeter should be to
read the manual
A low resistance conductor that is connected in parallel with the Ammeter’s digital display is called
a Shunt
in the Ohm setting, when you hold 2 test leads together, you should expect what reading
0 Ohms
When measuring amps, what protects the meter from having too much current running through it?
internal fuse
A high impedance meter should be used when reading electronics to reduce the
- Possibility of circuit damage
2. Inaccuracy of meter readings due to meter loading
What’s the term for measuring source voltage with no loads connected
Measuring open circuit voltage
An _______ _______ digital multimeter automatically sets itself to the most accurate range within each function
Auto Ranging
When checking _________, the meter is connected in parallel to the source voltage
voltage
When checking_________,the meter must be connected in series to allow the circuits current to flow through it
Amperage
Meters equipped with a ______ _______ have a battery to power the meters electronics.
Digital Display
If ___________ is reversed on a digital Multimeter, a ( - ) is displayed on the display
Polarity
You should always use a ______ _______ digital meter when measuring sensitive electronics
High Impedance
