1.2 Source Function

Resistance

This function generates the following resistances.

Range Source Range Notes

400Ω 0.00 Ω ~ 440.00 Ω Allowable measurement current: 0.1 mA to 3 mA 4000Ω 0.0 Ω ~ 4400.0 Ω Allowable measurement current: 0.05 mA to 0.6 mA

Resistance Source Method

A pseudo-resistance (R=V/I) is sourced by generating a voltage (V=R×I) corresponding to the

resistance [R] set on the instrument across the output terminals for the current for measuring

resistance [I] supplied to the device to be calibrated such as a resistance measuring

instrument and RTD thermometer.

Therefore, this instrument can be used only for instruments that measure pseudo-resistance

using a current for measuring resistance.

How to Source Accurately

• When measuring resistance using a two-wire system, use lead cables with low resistance.

Because the source resistance is calibrated without including the voltage drop of the

leaked cables, the lead cable resistance will result in error.

• To source the resistance accurately, use of the three-wire system or four-wire system.

1.2 Source Function

0% and 100% Values

These values become references for the source values when dividing or sweeping the source

values.

When the source is to be generated in divisions, the interval between 0% and 100% is divided

equally by a specified number, and the source value is changed stepwise through key operation.

In a linear sweep, the source value is varied linearly from 0% to 100% or from 100% to 0% over a

specified time period.

In a step sweep, the interval from 0% to 100% is divided equally by a specified number, and the

source value is automatically varied stepwise.

Number of Divisions

The interval between 0% and 100% is divided equally by a specified number, and the source value

is changed stepwise by operating the cursor keys (UP and DOWN keys).

For example, if 0% is set to 50 mV, 100% is set to 100 mV, and the number division is set to 4,

each time you press UP, the source value changes as follows: 0% (50 mV), 25% (62.5 mV), 50% (75

mV), 75% (87.5 mV), 100% (100 mV).

When the source range is 1-5V, 1-5V√, 4-20mA, 4-20mA√, or 4-20mA Simulate, the number

divisions is fixed to 4.

Wiring Systems

The following wiring systems are available: two-wire, three-wire, and four-wire.

Two-wire system: Because measurements include the resistance of measurement lead

cables and contact resistance, errors become large. Use this when the

resistance of the DUT is sufficiently larger then the resistance of the

measurement lead cables and contact resistance.

Three-wire system: By making the length of the three measurement lead cables the same,

measurements can be made without hardly being affected by the

resistance of the lead cables.

Four-wire system: Measurements can be made by eliminating the resistance of measurement

lead cables and contact resistance. Use this when you want to make

accurate measurements.

The instrument’s input terminal

Averaging

Moving average values for every five measured values and the maximum value (MAX) and

minimum value (MIN) of the moving average values are displayed on the screen.

0% and 100% Values

By mapping the output value (specified according to the specifications of the device to be

calibrated) to the 0% or 100% source value of this instrument, you can determine the output value

of the device to be calibrated for the source value.

For example, if the source value of 0% is 1 V and that of 100% is 5 V and the output values are

4 mA and 20 mA when 1 V and 5 V are input to the device be calibrated, assign 4 mA to the

measured value of 0% and 20 mA to that of 100%.

In this situation, the output value (specified according to the specifications of the device to be

calibrated) is 8 mA for a source value of 2 V of this instrument.

4 mA + (20 mA - 4 mA)×(2 V - 1 V)/(5 V - 1 V) = 8 mA

The CA550 calculates the error in the actual output value relative to the output value (specified

according to the specifications of the device to be calibrated) that is mapped to the source value.

Furthermore, this instrument calculates the measurement value percentages relative to the

specified 0% value and 100% value.

1.5 Calibration Function for Field Instruments

The following functions are available to efficiently calibrate field instruments.

1-5V Range

DC voltages from 1 to 5 V, which are common instrumentation signals, are generated in 1 V steps.

This is useful when calibrating the five input signals: 1 V, 2 V, 3 V, 4 V, and 5 V.

4-20 mA Range

DC currents from 4 to 20 mA, which are common instrumentation signals, are generated in 4 mA

steps.

This is useful when calibrating the five input signals: 4 mA, 8 mA, 12 mA, 16 mA, and 20 mA.

Program Sweep (CA550)

By using the CA550 program sweep function, you can assign instrument information such as the

calibration target model number, serial number, and tag number. The assigned information can be

saved as CSV data along with source values, measured values, and errors.

Because measured values, source values, errors, pass/fail judgment results, and the like can be

saved to a file automatically after a program sweep is completed, this is useful for recording data

before adjustment or data after adjustment.

Features

Errors and Pass/Fail Judgment (CA550)

The instrument determines the error in the actual output value of the device to be calibrated relative

to the output value (specified according to the specifications of the device to be calibrated) that is

mapped to the source value.

Moreover, the instrument indicates pass or fail depending on whether the measured value is within

the tolerance set in advance.

You can view the errors and pass/fail judgments in the files saved automatically by the program

sweep function.

Source Range

You can select from the following five source ranges.

Range Source Range

100 mV ±110.000 mV 1-5 V 0.0000 V to +6.0000 V 1-5 V√ 0.0000 V to +6.0000 V

Values for square root operation 5 V ±6.0000 V 30 V ±33.000 V

1-5V

The interval between 0% and 100% is equally divided by four, and the 0%, 25%, 50%,

75%, and 100% values are output. By default, because the 0% value is assigned to 1.0000

V and the 100% value is assigned to 5.0000 V, this can be used as a calibration signal for

instruments that use 1 to 5 V as input signals.

Square Root Commendation Function (1-5V√)

This can be used as a calibration signal for instruments that output the square root of input

signals.

Values for square root operation are generated.

Source Value

Voltages within each source range are generated.

In the default setting of the 1-5V range, 1 V to 5 V are divided into four, and 1 V, 2 V, 3 V, 4 V, and 5

V are generated.

In the default setting of the 1-5V√ range, 1 V to 5 V are divided into four, and values corresponding

to the square root of 1 V, 2 V, 3 V, 4 V, and 5 V are generated.

Source value = (%/100)×(%/100)×(100% value - 0% value) + 0%

In the default setting of the 1-5V√ range, 0% = 1 V and 100% = 5 V, so for 25% = 2 V,

Source value = (25/100)×(25/100)×(5 V - 1 V) + 1 V = 1.25 V.

4-20mA

The interval between 0% and 100% is equally divided by four, and the 0%, 25%, 50%, 75%,

and 100% values are output. By default, because the 0% value is assigned to 4.000 mA

and the 100% value is assigned to 20.000 mA, this can be used as a calibration signal for

instruments that use 4 to 20 mA as input signals.

Square Root Computation Function (4-20 mA√)

This can be used as a calibration signal for instruments that output the square root of input

signals.

DC currents corresponding to the square root of 4 mA, 8 mA, 12 mA, 16 mA, and 20 mA are

generated.

4-20 mA Simulate

Currents ranging from 0 to 20 mA that simulate transfer signals are generated. This can be

used to perform a loop check on the source value by connecting to a distributor or the like.

Currents within each source range are generated.

In the default setting of the 4-20mA and 4-20mA Simulate ranges, 4 mA to 20 mA are divided into

four, and 4 mA, 8 mA, 12 mA, 16 mA, and 20 mA are generated.

In the default setting of the 4-20mA√ range, 4 mA to 20 mA are divided into four, and values

corresponding to the square root of 4 mA, 8 mA, 12 mA, 16 mA, and 20 mA are generated.

Source value = (%/100)×(%/100)×(100% value - 0% value) + 0% value

In the 4-20mA√ range, 0% = 4 mA and 100% = 20 mA, so for 25% = 8 mA,

Source value = (25/100)×(25/100)×(20 mA - 4 mA) + 4 mA = 5 mA.

voltage or current is the value for square root operation.

Interval Time

The time period during which the source value of each step is held. You can specify 5 to 600 s.

Repeat

The interval for the signal to rise and fall or to fall and rise is considered a cycle. Set whether

to stop the sweep after one cycle (OFF) or repeat it (ON).

If set to OFF, sweeping stops after one cycle is executed, and sweeping stops, and the source

value is held.

If you change the sweep direction while sweeping is in progress, the source turns off when the

interval time elapses after reaching the 0% or 100% value after the change.

If you select ON, sweeping continues until the source is turned off with the OUTPUT ON/OFF

key.

Errors and Pass/Fail Judgment

The instrument determines the error in the actual output value of the measured calibration target

relative to the output value (specified according to the specifications of the device to be calibrated)

that is mapped to the source value and saves it as a percentage.

The instrument judges pass or fail depending on whether the value is within the tolerance specified

in the SETUP menu of Function 1.

Proper judgment cannot be made unless the 0% or 100% measurement value of this instrument is

assigned to the output value (specified according to the specification of the device to be calibrated)

that is mapped to the 0% or 100% source value of this instrument.
