Input Terminal Protection Limit

The protection limit applies to input terminals:

1． Main input (HI and LO) terminals

HI and LO terminals are used for Voltage, Resistance, Capacitance,

Continuity, Frequency and Diodes measurements and should be used under the following two conditions:

1) HI-LO protection limit: at most 1000 VDC or 750 VAC, this is also the maximum measurable voltage. The limit can be expressed as 1000 Vpk.

2) LO-ground protection limit: at most 500 Vpk (relative) is allowed to float at LO terminal with safety.

Since the HI terminal holds a maximum protection of 1000 Vpk relative to the ground, the sum of the “float” and measured voltages cannot exceed 1000

Vpk.

2． Sampling (HI Sense and LO Sense/200 mA) terminals

HI Sense and LO Sense/200 mA terminals are used for 4-Wire Resistance measurement and should be used under the following two conditions:

1) HI Sense-LO Sense/200 mA protection limit: 200 Vpk.

2) LO Sense/200 mA-LO protection limits: 0.5 Vpk. The current input fuse on the rear panel provides the current passing through LO Sense/200

mA up to 500 mA protection.

3． Current input (10 A and Sense/200 mA) terminals

10 A and LO terminals are used for current measurements of 2 A and 10 A.

The maximum current which goes through the 10 A terminal is limited to 10

A by the internal fuse. LO Sense/200 mA and LO terminals are used for current measurements ranging from 200 A to 200 mA. The maximum current which go through the LO Sense/200 mA terminal is limited to 500 mA by the internal fuse.

NOTE:

In order to prevent the fuse from blowing out and protect the multimeter, please use the current input terminals according to the following requirements:

1) Do not connect the 10 A and LO Sense/200 mA input terminals into the current measuring circuit at the same time.

IV User’s Guide for DM3068

RIGOL

2) Only use 10 A and LO terminals for measurements when the measured current AC+DC RMS value goes within 200 mA and 10 A.

3) Select a proper current input terminal according to the estimated current magnitude before connect the multimeter to AC supplies if you want to use current measurement.

4) The current into 10 A cannot exceed 13.5 A, otherwise it will blow out the internal fuse; while the current into the LO Sense/200 mA terminal cannot exceed 650 mA, otherwise the current fuse from the rear panel may be blown out.

IEC II Overvoltage Protection

In order to prevent electric shock, DM3068 provides overvoltage protection for line-voltage mains connections meeting both of the following conditions:

1． The HI and LO input terminals are connected to the mains under

Measurement Category II conditions, defined below.

2． The mains are limited to a maximum line voltage of 300 VAC.

WARNING: IEC II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipments and other devices that inserted into a branch socket.

DM3068 may be used to make measurements with the HI and LO inputs connected to mains in such devices (up to 300 VAC), or to the branch socket itself. However,

DM3068 may be used with its HI and LO inputs connected to mains from neither permanently installed electrical device such as a main circuit-breaker panel, sub-panel disconnected box nor wired motors. Such devices and circuits are readily to beyond the protection from DM3068.

NOTE: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, a transient overvoltage is also present in such circuits.

DM3068 was designed to safely withstand occasional transient overvoltage up to

2500 Vpk. Do not use this device to measure circuits whose transient overvoltage may exceed this level.

Temperature sensor

DM3068 can directly measure the temperature detected by TC (Thermocouple),

RTD (Resistance Temperature Detector) and THERM (Thermistor) sensors.

Different temperature sensor uses different form to convert temperature into electrical signal as its special characteristics. A temperature sensor that conforms to ITS-90 standards should be used for measurement.

 Done: saves and applies the current temperature sensor configurations.

For the connection method please see “Measurement Connections”.

The following parts introduce each temperature sensor supported by DM3068 in details.



RIGOL

TC

The TC (thermocouple) is one of the most common industrial thermometers. It converts the temperature value into voltage reading, and can measure temperatures in a wide range.

The common thermometers are B (Pt Rh 30- Pt Rh6), E (NI CR-WRCK), J

(Fe-WRCK), K (NI CR-NiSi), N (NiCrNi-NiSi), R (Pt Rh13 -Pt), S (Pt Rh10-Pt), T

(Cu-WRCK). Among them, B, R and S are precious metal thermocouple, while E, J,

K, N, T are cheap metal thermometers. For the reference table about each thermocouple, please see the ITS-90 standards.

The DM3068 provides two cold junction compensation modes: Internal cold

junction temperature & Simulated cold junction temperature.

Internal cold junction temperature refers to the internal temperature of the banana jack detected by the multimeter. Connect the thermocouple wire to the inside of the banana jack and prevent air flow from interfering the temperature around the banana jack. The radiating structure on the banana jack connected with the thermocouple wire would cause additional cold junction temperature error.

About 3-minute warm-up is needed to build up the thermal balance after the cold junction is connected.

Simulated cold junction temperature refers to the temperature at the cold junction compensation point of the thermocouple. The internal temperature of the banana jack might be different from the actual temperature at the cold junction compensation point. If external cold junction compensation equipment is used, the thermocouple voltage signal compensated can not be connected to the banana jack through the compensation lead, otherwise, additional cold junction error will be caused. The accuracy of the measurement when using simulated cold junction depends on the accuracy of cold junction compensation.

To use the TC sensor, you should select the type of the thermometer and the compensation mode of the cold junction as follows.

Press TC  Type to select desired thermometer type and press .

Press TC  JUNC, select INT or SIM to input correct cold junction temperature

(with -273 and 999) and then .

RTD

RTD is a resistance temperature detector commonly used in low temperature, having high measurement accuracy, stable performance and better linearity. It measures the temperature depending on the changing resistance of the measured substance with the temperature. The multimeter will display the temperature, corresponds to changing resistance.

The multimeter adopts the approximate algorithm of IEC751 standards and converts the resistance signal from the temperature sensor into the related temperature for displaying. For the reference table about each thermometer, please see related standards.

To use the RTD sensor, set the measurement parameters according to the following steps.

1. Set the R0 Value

Integration Time

Integration time is the period during which the multimeter’s analog-to-digital (A/D) converter samples the input signal for a measurement. The longer the integration time is, the slower the measurement speed and the higher the resolution; the shorter the integration time is, the faster the measurement and the lower the resolution. The integration time applies to DCV, DCI, 2WR and 4WR measurements.

DM3068 provides two types of ways to set the integration time:

 NPLC: expresses the integration time by the power line cycles, the unit is PLC.

It can be set to 0.006, 0.02, 0.06, 0.2, 1, 2, 10, 100, the default is 10. For the

relationship between the integration time and resolution, please see “Table

2-8”. The multimeter automatically detects the input power frequency when

power on and considers frequencies within 55 Hz and 66 Hz as 60 Hz and others as 50 Hz.

 APER: expresses the integration time by aperture time, the unit is s. It can be set from 100 μs to 1s, the default is 100 ms.

In DCV, DCI, 2WR or 4WR measurement, press  INTEG to enter the following interface.

To reduce the effects of loading errors and minimize noise pickup, you can set the input resistance of the multimeter to “>10GΩ” in the range of 200 mV, 2 V and 20

V, and “10MΩ” for the 200 V and 1000 V ranges.



RIGOL

True-RMS AC Measurements

The AC measurement of DM3068 has true RMS response. The power dissipated in a resistor over a period of time is proportional to the square of the measured true

RMS voltage, whatever the waveform shape is. The DM3068 can accurately measure the true RMS voltage and current if the waveform shapes whose energy beyond the effective bandwidth of the multimeter can be negligible. The effective

AC voltage bandwidth of DM3068 is 800 kHz and the effective AC current bandwidth is 100 kHz.

The multimeter's ACV and ACI functions measure the “AC coupled” true RMS value, that is to measure the RMS value of AC component (DC component is filtered) from the input signal. As shown in table 5-1, since the sine, triangle and square waves (50% duty cycle) do not have DC offset; each wave has an equal value in

AC and AC+DC.

Non-symmetrical waveforms such as pulse trains contain DC component which will be filtered during the AC coupled true RMS measurements.

The AC coupled true RMS measurement is especially useful for measuring small AC signals having DC offset such as the AC ripple from DC power supplies. However, in fewer cases the AC+DC true RMS value must be measured. First you can

Chapter 5 Measurement Tutorial determine the DC and AC components of the signal by using DCV and ACV measurements, and then substitute the results in the formula given below and work out the AC+DC true RMS value.

Crest Factor Errors (non-sinusoidal inputs)

A common misconception is that "since an ac multimeter is true RMS, its sine wave accuracy specifications apply to all waveforms." Actually, the shape of the input signal can dramatically affect measurement accuracy. A common way to describe signal wave shapes is “crest factor”. Crest factor is the ratio of the peak value to

RMS value of a waveform.

In general, the greater the crest factor, the greater the energy contained in high frequency harmonics. All multimeters have errors that are relevant to crest factor.

Crest factor errors from DM3068 are listed in “AC Characteristics” section in

chapter 6.

You can estimate the measurement error due to signal crest factor as shown below:

Total Error＝Error (Sine wave) + Error (Crest factor) + Error (Bandwidth)

Error (Sine wave): sine wave error as shown in chapter 6.

Error (Crest factor): additional crest factor error as shown in chapter 6.

Error (Bandwidth): estimated bandwidth error as shown below:

Example:

Calculate the approximate measurement error for a pulse train input with a crest factor of 2 and a fundamental frequency of 20 kHz. Then, assume the multimeter’s

1-year accuracy is ± (0.05%× reading + 0.03%× range).

Total Error = (0.05%× reading + 0.03%× range) + (0.05%× range) +

(0.8%× reading) =0.85%× reading + 0.08%× range
