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 defined as follows:
The user-replaceable 10 A current-protection fuse is on the front panel. To
maintain protection, replace fuse only with fuse of the specified type and rating.
About the specified type and rating of the fuse, please refer to "7 Current Terminal
Fuse" in "Front Panel Overview" on page 9.
Main Input Terminals (HI Input and LO Input) Measurement
Limits
The HI and LO input terminals are used for voltage, resistance, continuity,
frequency (period), capacitance, diode, and temperature test measurements. Two
Measurement Limits are defined for these terminals:
HI Input to LO Input Measurement Limit
The Measurement Limit from HI Input to LO Input is 1000 VDC or 750 VAC,
which is also the maximum voltage measurement. This limit can also be
expressed as 1000 Vpk maximum.
LO Input to Ground Measurement Limit
The LO input terminal can safely "float" a maximum of 500 Vpk relative to
ground, where ground is defined as the Protective Earth Conductor in the AC
mains power cord connected to the instrument.
As implied by the above limits, the Measurement Limit for the HI input terminal is
a maximum of 1500 Vpk relative to ground when LO Input is at its maximum of
500 Vpk relative to ground.
1.General Safety Requirements
4
Current Input Terminal (I) Measurement Limits
The Measurement Limit from the current input terminal (I) to the LO Input terminal
is 10 A (DC or AC). Note that the current input terminals will always be at
approximately the same voltage as the LO Input terminal, unless a current
protection fuse is open.
Sense Terminals (HI Sense and LO Sense) Measurement
Limits
The HI and LO sense terminals are used for four-wire resistance measurements.
The Measurement Limit from HI Sense to LO Input is 200 Vpk.
The Measurement Limit from HI Sense to LO Sense is 200 Vpk.
The Measurement Limit from LO Sense to LO Input is 2 Vpk.
Note: The 200 Vpk limit on the sense terminals is the Measurement Limit.
Operational voltages in resistance measurements are much lower – up to ± 12 V
in normal operation.
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.
1.General Safety Requirements
5
Measurement category definition
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 energyconsuming equipment supplied from the fixed installation, such as TVs, PCs,
portable tools, and other household circuits.
Measurement CAT III applies to protect against transients in equipment in fixed
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.

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 by transportation.
If it is found that the packaging carton or the foamed plastic protection cushion
has suffered serious damage, do not throw it away first 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 the distributor of
PEAKTECH responsible for this service or the PEAKTECH's local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
instrument can not work normally, or fails in the performance test, please get in
touch with the PEAKTECH's distributor responsible for this business or the
PEAKTECH's local offices. If there is damage to the instrument caused by the
transportation, please keep the package. With the transportation department or
the PEAKTECH's distributor responsible for this business informed about it, a
repairing or replacement of the instrument will be arranged by the PEAKTECH.

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 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.
17
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.
The range of continuity test is fixed at 2 kΩ; the range of diode measurement is fixed at
2 V.
18
Measurement Speed and Resolution
The instrument provides three types of measurement speed:
"Low" speed is 5 reading/s; "Mid" speed is 50 reading/s; "High" speed is 150
reading/s.
In DCV, ACV, DCI, ACI and 2-wire / 4-wire resistance measurements, the
measurement speed is selectable.
The reading resolution of P4095 is 4½.
The reading resolution of P4096 can be 4½ or 5½ digits. The selection of
measurement speed affects the reading resolution. The multimeter automatically
selects a reading resolution according to the current measurement settings.
