1.Safety Information
Measurement Limits
The protection circuitry of the multimeter can prevent damage to the instrument
and protect against the danger of electric shock when the Measurement Limits
are not exceeded. To ensure safe operation of the instrument do not exceed the
Measurement Limits shown on the front panel it is dened as follows:
Main Input Terminals Measurement Limits
The Input and COM Input terminals are used for voltage resistance
continuity frequency (period) capacitance diode and temperature test
measurements. The Measurement Limit is dened for these terminals:
Input to COM Input Measurement Limit
The measurement limit from Input to COM Input is 1000 VDC or
750 VAC which is also the maximum voltage measurement. This limit can
also be expressed as 1000 Vpk maximum.
Current Input Terminal Measurement Limits
The measurement limit from 10A input terminal to COM Input terminal is 10A
(DC or AC).
The measurement limit from μA mA input terminal to COM Input terminal is
600mA (DC or AC).
Note that the current input terminals will always be at approximately the same
voltage as the COM Input terminal.
Measurement Category
The safety rating of the multimeter:
1000 V, CAT I
IEC Measurement Category I. The maximum measurable voltage is 1000 Vpk in
the HI -LO terminal.
600 V, CAT II
IEC Measurement Category II. Inputs may be connected to AC mains power (up
to 600 VAC) under Category II overvoltage conditions.
Measurement category denition
4

1.Safety Information
Measurement CAT I applies to measurements performed on circuits not directly
connected to the AC mains. Examples are measurements on circuits not derived
from the AC mains and specially protected (internal) mains- derived circuits.
Measurement CAT II applies to protect against transients from energy-
consuming equipment supplied from the xed installation such as TVs PCs
portable tools and other household circuits.
Measurement CAT III applies to protect against transients in equipment in xed
equipment installations such as distribution panels feeders and short branch
circuits and lighting systems in large buildings.
Measurement CAT IV applies to measurements performed at the source of the
low- voltage installation. Examples are electricity meters and measurements on
primary over current protection devices and ripple control units.

1.Safety Information
2. Quick Start
General Inspection
After you get a new multimeter it is recommended that you should make a check
on the instrument according to the following steps:
1. Check whether there is any damage caused y transportation.
If it is found that the packaging carton or the foamed plastic protection cushion
has suered serious damage do not throw it away rst till the complete device
and its accessories succeed in the electrical and mechanical property tests.
2. Check the Accessories
The supplied accessories have been already described in the Appendix A:
Enclosure of this Manual. You can check whether there is any loss of
accessories with reference to this description. If it is found that there is any
accessory lost or damaged please get in touch with our distributor
responsible for this service or our local oces.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument or the
instrument cannot work normally or fails in the performance test please get
in touch with our distributor responsible for this business or our local oces. If
there is damage to the instrument caused by the transportation please keep
the package. With the transportation department or our distributor responsible
for this business informed about it a repairing or replacement of the
instrument will be arranged by us.

3. Functions and Operations
To Set the Range
The instrument provides auto and manual range. In auto range the multimeter
selects a proper range automatically according to the input signal; in manual
range you can use the front panel key or menu softkey to set the range. The auto
range can bring a lot of convenience for users while the manual range provides
higher reading precision.
1st Method: Use the front panel key to set the range.
When the Range softkey is shown on the right menu you can press the
key to switch between auto and manual range. Press or keys to enable
manual range and increase or decrease the measurement range.
2nd Method: Select the range in the measurement function menu.
Select auto range: In the measurement function menu press the Range softkey
select Auto.
Select manual range: In the measurement function menu press the Range
softkey select a range except Auto.
Note:
 When the input signal exceeds the current range "overload” will be displayed.
 By default the range is set to Auto at power-on or after a reset.
 Auto range is recommended if you are not sure about the measurement range
in order to protect the instrument and obtain accurate data.
