Max display: 1999 counts with automatic polarity indication
Indication method: LCD display
Measuring method: Dual slope integration A/D converter system
Over range indication: 1 shown in the display
Reading rate time: 2-3 readings per sec.
Input impedance: ≤ 10Mohm
Accuracy: ± 0.5% (23±5℃ <80%RH)

If you need add proper voltage dividers ( RA, RB are not included ) and decimal point wire jumper:
Proper voltage divider
Note : RA & RB must be more than 1/4W 0.5% metal film resistors or best and higher
B, Connect an 8-12V power supply to panel meter
C, For ranges other than 200mV, input accurate 1/2 X max. Voltage generated by calibrator and carefully adjust semi fixed resistor 201 to have the same reading in LCD
D, Connect the input voltage or current to be measured to IN and COM, the input voltage should be DC only
E, Connect the power to “+” and “-”polarity
