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

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.

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

To reduce the effects of loading errors and to minimize noise interference, set the
multimeter's input resistance to 10 GΩ for the 200 mVDC and 2 VDC ranges. The
input resistance is maintained at 10 MΩ for the 20 VDC, 200 VDC, and 1000 VDC
ranges.

True RMS AC Measurements
The AC measurement of the multimeter has true RMS response. Power
dissipated in a resistor is proportional to the square of an applied voltage,
independent of the wave shape of the signal. This multimeter accurately
measures true rms voltage or current, as long as the wave shape contains
negligible energy above the meter’s effective bandwidth.
The effective AC voltage bandwidth of the multimeter is 100 kHz, while the
effective AC current bandwidth is 10 kHz.

The multimeter's AC voltage and AC current functions measure the AC-coupled
true rms value, the RMS value of only the AC components of the input waveform
are measured (DC is rejected). As seen in the figure above; for sine waves,
triangle waves, and square waves, the AC–coupled and AC+DC values are equal,
because these waveforms do not contain a DC offset. However, for non–
symmetrical waveforms (such as pulse trains) there is a DC voltage content,
which is rejected by the multimeter’s AC–coupled true rms measurements.
The AC coupled true RMS measurement is especially useful for measuring small
AC signals in the presence of large DC offsets. For example, this situation is
common when measuring AC ripple present on DC power supplies. However,
there are situations where you might want to know the AC+DC true RMS value.
You can determine this value by combining results from DC and AC
measurements, as shown below:

For the best AC noise rejection, you should select "Low" measurement speed to
get 5½ digits reading resolution when performing the DC measurement.

Loading Errors (AC Voltage)
In the AC voltage function, the input impedance of the multimeter appears as a 1
MΩ resistance in parallel with 100 pF of capacitance. The cabling that you use to
connect signals to the multimeter also adds capacitance and loading. The table
below shows the multimeter's approximate input resistance at various
frequencies.

5. Troubleshooting
1. The instrument is powered on but no Display.
1) Check if the power is connected properly.
2) Check if the AC Mains Line Voltage Selector is in the proper voltage scale.
3) Check if the line fuse which is below the AC Mains Input is used
appropriately and in good condition (see page 69, Appendix C: Line Fuse
Replacement).
4) Restart the instrument after the steps above.
5) If the problem still exists, please contact PEAKTECH for our service.
2. The reading does not change when a current signal is input.
1) Check whether the test lead is correctly inserted into the current input
terminals (I terminal and LO Input terminal).
2) Check whether the current terminal fuse at the front panel is burned out.
Please refer to "7 Current Terminal Fuse" in "Front panel overview" on page
9.
3) Check whether the DCI or ACI measurement function is enabled.
4) Check whether the DCI measurement function is used to measure AC
current.
If you encounter other problems, try to reset the settings or restart the instrument.
If it still can not work properly, please contact PEAKTECH for our service, and
provide your device information. ( → Next → System Info)
