Do not use abrasives or solvents on the meter. To clean it use only a
damp cloth and mild detergent.
GENERAL DESCRIPTION
This compact digital multimeter is designed to measure AC and DC
voltage, AC and DC current, Resistance, Capacitance, Diode and to
perform audible continuity checks with accuracy and ease.
Small and light weight, with a carrying case and test leads wound on
its body, this instrument will provide you years of satisfactory service.
SPECIFICATION
Accuracy is specified for one year after calibration, at operating
temperatures of 18
℃
to 28
℃
, with relative humidity at 0% to 75%.
