Pollution Degree

Pollution Degree applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand voltage or surface resistivity. The pollution degree of the CA150 in the operating environment is 2. Pollution Degree 2 applies to normal indoor atmospheres. Normally, only non-conductive pollution is emitted. However, a temporary electrical conduction may occur depending on the concentration.

Note

• For accurate source and measurement, operate the CA150 in the 23 ± 5C temperature range and 55 ± 10% RH.

• Condensation may occur if the CA150 is moved to another place where the ambient temperature and humidity are higher, or if the temperature changes rapidly. If this happens, let the CA150 adjust to the new environment for at least two hours before using it.

Before Starting Generation or Measurement

Input Inductance Component

• The current source function of the instrument may result in an unstable output if the instrument is connected to, for example, a positioner or electropneumatic converter having a large input inductance component. Make sure the input inductance component of the equipment to be connected is no greater than 100 H.

• If the equipment's input inductance component is unknown, connect the instrument to the equipment as shown in the figure below, and measure the generated current at the MEASURE side. If the reading does not stabilize or an accuracy error results at that point, the input inductance component is likely to be greater than 100 H.

• If the equipment's input inductance component is too large, connect a 200- resistor R and a 1-F capacitor C to the instrument's outputs, as shown in the figure below. This setup makes it possible to connect an input having an inductance component of up to 3 H to the instrument. Note, however, that the instrument's response time becomes 1 second (at load resistances no greater than 2 k). Do not use this circuitry for purposes other than current generation (DCA), otherwise errors may be produced.

4.4 Source Resistance () Signals

Procedure for Generating Resistance Signals

• The instrument generates a resistance signal by receiving the resistancemeasuring current I supplied from the device under calibration (resistance meter, RTD thermometer, etc.) and delivering the voltage V = R  I proportional to the preset resistance R between the output terminals, and thus producing the equivalent resistance R = V/I. Consequently, the instrument generates the signal correctly only for such devices that employ this method of measurement.

• The allowable range of the resistance measuring current I that the instrument receives from a resistance measuring device under calibration is rated as

0.01 to 5 mA. (This varies depending on the generated resistance value. For details, refer to the specifications.)

Obtaining Accurate Measurements

• Since the generated resistance value is calibrated without including the voltage drop component of the lead cables, the resistance (approximately 0.1  on a round-trip basis) of the lead cables becomes an error in the case of a load current.

• For accurate generation of resistance signals, use a three-wire connection for output. (Refer to the figure below.)

• If the capacitance between the terminals of a device under calibration is greater than 0.01 F, the instrument may be unable to generate correct resistance values.

5. Measurement

Warning

•Turn off the power supply to the object to be tested before connecting it to the instrument. It is extremely dangerous to connect and disconnect measurement lead cables while power is being supplied to the object.

• It is extremely dangerous to incorrectly connect the voltage input terminal H and the current input terminal mA. Make sure that the measurement function (FUNCTION) selection and terminal connections are correct. An incorrect connection may not only cause damage to the circuit or device under test and the instrument, but also result in injury to the operator.

• The maximum allowable applied voltage for the grounding of all input/output terminals is 42 Vpeak. Be sure not to exceed this voltage because doing so may not only cause damage to the instrument, but also result in injury to the operator.

Caution

About the Fuse

There is a built-in current input protection fuse for the current input terminal. The fuse blows when an excessive current flows. If the fuse does blow, be sure to replace it with the designated fuse (model: A1566EF). For details on the procedure for replacing the fuse, refer to "3.2.4 Fuse."

Caution

● About Resistance (500 ) Internal Offset Calibration *: When performing zero point calibration, make sure the voltage between the

H and L terminals is within approximately 20 V (0.02 mV). If this value is exceeded, the instrument needs to be repaired (internal calibration).

● About Resistance Excitation Current

When calibrating the 500  and 5 k ranges, two types of calibration are required because of differences of current (excitation current) inflowing from an external device.

L 500 , 1 mA Calibration with the resistance measurement range of a L 5 k, 0.1 mA digital multimeter is possible. During calibration, make

sure the resistance measurement current is the current value shown on the left.

H 500 , 5 mA Apply the current shown on the left from an external device H 5 k, 0.5 mA as shown in connection diagram <4> and then measure

the voltage drop and perform calibration.

9.1 Calibration of Source Functions (Adjustment)

Tip

•You can select to calibrate just the functions and ranges that require calibration. (Be sure to perform both zero point and full scale (FS) calibration of the same range together.)

• Calibration of thermocouple (TC) and resistance temperature detector (RTD) takes place at the same time as calibration of the100 mV and 500  ranges.
