Transfer-type instruments
All
An electrodynamic type instrument finds its major use as:
standard instrument only
both as standard and transfer instrument
transfer instrument only
indicator-type instrument
Sensitivity of a voltmeter is expressed in
V/Ohm
Ohm/V
Ohm/A
V/A
What is the axial strain?
length/change in length
change in length/change in area
change in area/change in length
change in length/length
Having a accelerometer, which of the following size is not used to be measured?
vibration
shock
acceleration
velocity
Wien-bridge, in its basic form is used to measure unknown:
inductance
capacitance
frequency
resistance
Time base signal (saw tooth signal) of an analog oscilloscope means:
sweep time + fly back time
only fly back time
only sweep time
fly back time + sweep time
When evaluating the performance of an oscilloscope, a thing you might consider is:
the bandwidth
the DAC resolution
the horizontal sensitivity
the sweep speed
The difference between digital storage osc (DSO) and digital phosphor osc (DPO) is:
The DSC has a higher bandwidth
The DSO has a color display
The DPO captures 3D information of waveform in real-time
the DSO captures more signal details
What thermistor is more widely used in real live?
NTC
TTC
ATC
DTC
