The equipment of clamp type multi product multimeter calibrator is
compliance with national verification regulation: JJG124-2005
“Ammeter, voltmeter, power meter and resistance meter verification
rules” and related national standards. 0.05 single-phase AC/DC
standard source, can verify magnitude 0.2 and the following AC/DC
voltmeter, ammeter, frequency meter, resistance meter. The source
signals by using DSP and 16-bit high-speed analog-to-digital
converters of controllable sine wave, the distorted wave signal
source.The equipment comes with RS-232 interface, can be connected
with PC to a semi-automatic verification system. It has precise
interface and multi-functions including verification, storage and
query.The equipment adopts color LCD screen, chart character
display is clear, with high precision, stable and reliable,
convenient operation and flexible characteristics.
Theory
Calibration of multimeter in measurement technology and metrology
is the comparison of measurement values delivered by a device under
test with those of a calibration standard of known accuracy. Such a
standard could be another measurement device of known accuracy, a
device generating the quantity to be measured such as a voltage, or
a physical artefact, such as a metre ruler.
The outcome of the comparison can result in no significant error
being noted on the device under test, a significant error being
noted but no adjustment made, or an adjustment made to correct the
error to an acceptable level. Strictly speaking, the term
calibration means just the act of comparison, and does not include
any subsequent adjustment.
The calibration standard of multimeter and clamp meter is normally
traceable to a national standard held by a National Metrological
Institute.
