Description:

Meter use direction vertical
Standard test conditions Temperature 20 ° C, humidity 70%, for the test results do not differ,
Can also be tested under normal temperature and humidity
Current sensitivity Pointer from zero scale to maximum scale (full scale position) Sensitivity 260 uA ± 10 %
Internal impedance 650 Ω ± 10 %
The external insulation of the meter and the electrical circuit are 500V DC plus 50M ohm. The insulation resistance of the meter case and the electrical circuit is tested by the 500V DC voltage.
Zero position The meter uses the standard posture, and the front end of the pointer is integrated with the center of the zero scale.
The tolerance of the pointer and zero scale overlap is ±1mm
Equilibrium The allowable error range of the meter when the standard position is tilted 90 degrees back and forth ±1mm When the pointer is stuck, the current is tripled and the current is tripled, and the current is gradually reduced to 1/2 of the current sensitivity.
At this point, the pointer will return to the scale of 1/3 scale.
Friction When the current is added to the meter and slowly increased or decreased to a certain value, the error range of the indication point is ±1mm.
Brake instant plus the current value of the scale 2/3, within one second from the start to the time required for the pointer to indicate the position
Operating temperature limit -10°C to+60°C RH 35 to 85%
Storage temperature limit -20°C to+60°C RH 35 to 85%
Do not place the meter in direct sunlight and store the meter in the box to prevent foreign matter from entering the meter.

Packing: 1pc P-59 VU meter
