Features:
Premium quality, cute appearance, stable and reliable performance, Display high precision and with backlight.
Part No. TR-35
Professional, high Class
dB : -20~+5dB
0dB=1.288V+/-10%, calibalated
DCR= 650Ω, If=450uA
Lamp : White LED x1pcs ,10~20mA (Original design has no resistor inside, so need extra one to work)
Led Lamp voltage : 2.2~2.6V
So, you need the extra resistor : 270Ω 1/4W ,if VDC=5V
390Ω 1/4W ,if VAC/DC=6.3V
1000Ω 1/2W ,if VAC/DC=12.6V
Also need external resistor,diode, capacitor
(if 1Khz 0dB=1.288Vrms, R1=470Ω,VR1=100Ω, or R1+VR1=500Ω)
Dimension : 35.0x35.0x38.0mm, WxHxD
View size : φ34.0mm
Mounting hole/pitch : φ3.5mm/28.0x28.0mm
Note: On the center 2 pins are for meter coil, other 2 pins are for LED
