True RMS Multimeter

1.Introduction

Professional True RMS Industrial D igital Multimeter with osci l loscope functions and TFT
color LCD display ,providing fast A/D conver ting sampling time, high accuracy , built-in
datalogging and Trend Capture feactures. It can trace any interrupted problems of the equipments
and watch on without person. It is easy to find and solve the problems of the production
equipments, providing Bluetooth technology and memory the datasheets. It is much more safe
measurements with double molded plastic housing design and IP67 waterprooff unction.
This meter measures AC/DC Voltage, AC/DC Current, Resistan ce,Capacitance,Frequency
(electrical & electronic), Duty Cycle, Diode Test,Insulation Test,and Continuity plus Thermocouple
Temperature. It can store and recall data. It features a waterproof, rugged design for heavy duty
use.Proper use and care of this meter will provide many years of reliable service.

2.Safety

This symbol adjacent to another symbol, terminal or operating device indicates that the
operator must refer to an explanation in the Operating Instructions to avoid personal injury
or damage to the meter.
WARNING This WARNING
avoided, could result in death or serious injury.
CAUTION This CAUTION
avoided, may result damage to the product.
This symbol advises the user that the terminal(s) so marked must not be connected to a
MAX
circuit point at which the voltage with respect to earth ground exceeds (in this case) 1000
VAC or VDC.
This symbol adjacent to one or more ter minals identifies them as being associated with
ranges that may, in normal use, be subjected to particularly hazardous voltages. For
maximum safety, the meter and its test leads should not be handled when these terminals
are energized.
This symbol indicates that a device is protected throughout by double insulation or
reinforced insulation.
PER IEC1010 OVERVOLTAGE INSTALLATION CATEGORY
OVERVOLTAGE CATEGORY I
Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to circuits in which
measures are taken to limit the transient overvoltages to an appropriate low level.
Note – Examples include protected electronic circuits.
