5135A Universal Digital Panel Meter
I Product Highlights
This Meter is a 3 ½ Digits Panel Meter, is great for measurements that require high precision and stability. It is widely used to measure and display of voltage, current as well as other critical parameters in variety of electrical equipments and instruments.
Surface Mount Technology (SMT) has been adopted for meter’s PCB mass fabrication, which greatly increases the product quality.
Can be used as Voltmeter, Amp meter, or general readout display.
Accuracy adjustment.
Decimal point position adjustable.
Hold current reading is available.
Digital filter at input can be turned ON or OFF.
Capable of measuring its own supply voltage source.

III Operation Instruction
a) Accuracy Adjustment: measure a know voltage and turn the knob on the blue variable resistor to the know value. Adjustable range would be around +/-100.
b) Display Memory: Short the two points where marked “M” to activate memory.
c) Digital Filter: Short the two points where marked “C” to activate digital function, which can filter out noises and input signal fluctuation.
d) Decimal Point setting: By using D1,D2 and D3.
When nothing shorted, no decimal point is displayed.
When D1 is shorted, decimal is between two right most digits
When D2 is shorted, decimal is between two center digits
When D3 is shorted, decimal is between two left most digits.
e) Expansion of measurement range:
Obtain right measurement range by changing resistors according to the following table.

Resistor requirements:
Resistors with 1.0% error rating, some adjustment of the variable resistance might be needed to obtain accuracy.
Resistors with 0.1% error rating, can be directly used without adjustment.
