CE Approval Cos Meter Analog Panel MeterUses and applications:This
series of meters is a direct imitation of power measurement display
instruments, measuring DC current and voltage, AC current and
voltage, frequency, power factor, phase sequence, power,
synchronization instructions and other non-power measurements. It
has been widely used in a variety of AC and DC transmission and
distribution systems, power control panels and other electrical
devices, in the industries of maritime shipping, rail transport,
chemical flameproof, low voltage equipment, construction equipment,
generators, machinery equipment, etc. Being able to make electrical
measurement and non-power measurement, it is a high-end instrument
applied in general environmental conditions.Standards and
certifications:The Jingying series of pointer meter is
produced on the standard of GB/T7676-1998, and the digital meter is
on the standard of GB/T22264-2008. Its safety performance is on the
standard of GB4793 and IEC61010. The dial scale line and the
pointer is designed to meet the German standards of DIN43790 and
DIN43802. The shape and hole size of the meter is on the standards
of GB/T1242 and IEC61554. All the products of Jingying meters
Company have gone through the national CE certification, and have
got ISO: 9001 certification.The outer casing of the panel meter:The
base of the series of JY meters is made of TBT flame-retardant
plastic, and its vicat temperature is 130. The outer shell is made
of ABS flame-retardant plastic, and its vicat temperature is
85.Changes caused by the temperature:Temperature range for
reference: 23 be out of the range of the level index ±
100%.Accuracy level:The JY series of pointer meter: AC and DC
voltmeter and ammeter to the level of 1.5 or 2.5, power meter to
the level of 2.5, frequency meter to the level of 2.5, and power
factor meter to the level of 2.5.Extrinsic current shunt:The
voltage specifications of the extrinsic current shunt of DC
ammeters are 150mV, 100mV, 75mV, 60mV and 50mV, which can be
customized. The resistance of the conducting wire connecting the
meter and the current shunt should within the range of 1525mΩ , to
ensure the accuracy of the meter.The surface of the dial:The
surface of the dial uses aluminum alloy, white paint, black ink
printing or laser printing. The dial can be customized according to
the customer's sample dials (overprint colors can be customized).
The luminous dial uses the PC panel.Nameprecisionnormal
