Theory of Operation

3-1. INTRODUCTION

3-2. This section of the manual contains an overall functional description and a brief circuit analysis of the 2180A Digital Thermometer. Simplified circuit diagrams are provided, as necessary, to supplement the text. Detailed schematics are given in Section 8 of this manual.

3-3. The Model 2180A is a single point RTD Digital Thermometer with 0.1° and .01° resolution for either degrees F or C. This instrument features dual slope A/D conversion, microcomputer control logic, and a 5-digit display with temperature scale indicator. Various RTD types can be used over a temperature range of -394° F to

1435°F (-219°C to 664°C). Refer to Figure 3-1 for the following functional description. Mnemonic definitions are provided in Table 3-1.

3-4. FUNCTIONAL DESCRIPTION

3-5. The Model 2180A executes a continuous series of measurement cycles. These cycles, controlled entirely by a microcomputer, include three major periods: the AutoZero, the Integrate, and the Read periods. During each period, digital controls are applied to the analog section of a dual slope converter. The converter in turn generates a compare output. The configuration of the analog section during each phase of the measurement cycle is established by the condition of microcomputer controlled

FET switches.

3-6. The measurement cycle begins with the Auto-Zero period. During this period, the input to the Buffer Amplifier is connected to ground through an FET switch and the accumulated dc offset voltages present in the analog section are sampled and held by the Auto-Zero capacitor. This voltage is used later in the measurement cycle to cancel measurement errors introduced by offset voltages in the analog circuitry. The final measurement is

therefore proportional to the RTD probe output voltage and does not include offset errors.

3-7. During the Integrate period, the RTD input voltage read across the RTD, is applied to the integrator. The algebraic sum of the AZ and RTD input voltages is integrated over a 100 ms period. At the end of this period, the RTD input voltage is removed from the integrator, and the Read period is started.

3-8. A reference voltage is applied to the integrator during the Read period, causing the integrator capacitor to be discharged at a linear rate. When the integrator output reaches zero, a compare signal is generated to end the Read period. The duration of the Read period is translated by the microcomputer, to provide a digital indication of the RTD temperature.

3-9. CIRCUIT ANALYSIS

3-10. Circuit analysis of the 2180A is discussed in two sections: digital and analog. The digital section is covered first; particular attention is paid to digital control of the analog section. The analysis of the analog section covers the analog measurement circuitry and the 2180A power supply.

3-11. Digital Section

3-12. The digital section of the 2180A consists of a single-chip microcomputer with a self-contained, programmed, read only memory (U9), a hex CMOS open drain buffer (U13), and an LED display. This section, shown in Figure 3-2, will provide the following functions:

1. Conversion of the non-linear RTD probe voltage, as measured by the analog section, into a linear digital display.

2. Control of the analog section.

3. Control of all accessories on the accessory bus.

type of RTD. One of the seven operating programs is selected for the RTD type by setting S1 on the RTD Input

Module. A table showing RTD switch setting numbers and corresponding RTD types is printed on the RTD Input Module PCB.

3-14. Measurement data is continuously strobed out of the microcomputer in decoded-seven-segment, bitparallel, character-serial format. This data is then sent to the LED display.

3-15. The total measurement cycle takes 300 ms. The cycle consists of the following periods:

1. Auto-Zero period (100 to 200 ms).

2. Integrate period (100 ms). A 1 ms nominal hold signal is inserted at the beginning and end of the Integrate period to accomodate settling times in the analog section.

3. Read period (variable 0 to 100 ms).

3-16. Analog Section

3-13. The microcomputer (U9) contains all of the 2180 A programming, control logic, and linearizing capability. It also provides all signals necessary to update the display.

Linearization of the RTD signal is accomplished by using a piece-wise, 4th order, curve-fit approximation for each

and a combination of FET switches. Refer to Figure 3-3 in conjunction with the following individual circuit descriptions. All FET switches will be shown in their open state; they are closed during measurement cycle commands from the 2180A’s digital section.

3-19. The RTD Input circuit comprises the RTD probe, the RTD Input Module, and a low pass filter on the Input

Module’s PCB. Source current flows through a series

combination of the RTD probe, R2 (RTD Input

Module), and R1 (Main PCB). The voltage sensed across the RTD is routed through the Input Module, and onto the Main PCB. The TSense line (always a positive voltage) is then applied to the low pass filter.

DE+

f^o

U16

3-20. The ground sense amplifier (Q20, U7 and associated circuitry) maintains the -Sense line at measurement ground. This amplifier compensates for noise and offsets on the -V and -Sense lines.

3-21. To achieve switching between 0.01° and .1° resolution, the buffer gain is shifted by a factor of ten. For

0.01° resolution, FET switch Q17 is on, and a reference voltage of-100 mV is applied to the buffer (Q19, U5). The buffer gain is set to 100. For 0.1° resolution, FET switch Q16 is on, and a reference voltage of -1 .OOV is applied and the buffer gain is 10.

3-22. The first voltage reference consists of a resistor network supplied by an accurate 6.2V dc reference voltage. The resistive divider network is set to provide 200 mV to Q14, lOOmVtoQ15, l.OVtoQl l,and2.0VtoQlO.

When 0.01° resolution is in use, Q12 will allow reference capacitor C19 to attain a -100 mV charge. For 0.1° resolution, Q8 will allow C20 to charge to ° l.OV. Either reference capacitor will be placed at the -Sense level during Auto-Zero. Recovery deintegrate is applied to QIO and Q14.

3-23. A second voltage reference (U15-6) provides an accurate 6.2V across the series combination of R1 (Main Thermometer PCB), R2 (RTD Input PCB), and the

RTD. This voltage therefore provides the source (+V) voltage for the RTD.

3-24. The Buffer, Integrator, Gain Stage, and

Comparator Amplifiers combine to perform the analog functions of the Integrate, Read, and Auto-Zero periods. The Buffer is used to provide integrator inputs during all three periods. The Integrator integrates the Buffer output voltage during the Integrate and Read periods and, in combination with the Gain Stage, functions as a closedloop amplifier during the Auto-Zero period.

3-25. An Auto-Zero period is commanded during the first phase of each measurement cycle. During this time, five auto-zero switches (Q4, Q5, Q11, Q15, and Q22) are closed by the microcomputer. Three of the switches (Q11, Q15, and Q22) charge the reference capacitors to +100 mV on Cl9 and +1.0V on C20. Closing switch Q4 connects the Integrator and Gain Stage into a closed-loop configuration. This action also allows the Auto-Zero capacitor (Cl2) to charge to a value proportional to the algebraic sum of all the offset voltages in the Buffer,

Integrator and Gain Stage. At the end of the Auto-Zero period, switches Q4, Q5, Q11, Q15, and Q22 are opened. The reference capacitors (Cl9 and C20) and the AutoZero capacitor retain their charges for later use in the

measurement cycle.

Read mode is enabled. Similarly, a negative Read mode is enabled when a negative input is sensed.

3-28. When the positive Read mode is commanded, FET switches Q13 and Q9 are closed. If 0.1° resolution is in effect, Q8 will place the positive side of reference capacitor C20 at ground. With 0.01° resolution in effect, Q12 will place the positive side of reference capacitor Cl 9 at ground. Reference capacitors C20 and Cl9 will then apply either -1 .OV or -100 mV, respectively, to the Buffer input.

3-29. When the negative Read mode is commanded, switches QIO and Q14 are closed; Q9 and Q13 are open. With .01° resolution selected, approximately +200 mV will be applied to the positive side of reference capacitor Cl9. The algebraic sum of the voltage at the Buffer input will then be +100 mV. When 0.1° resolution is selected, approximately +2.0V will be applied to the positive side of reference capacitor C20. Buffer input voltage will then be +1.0V (only during recover deintegrate).

3-30. After a 1 ms settling time, switch Q7 closes and the Buffer output voltage is applied to the Integrator input. The integrator capacitor now begins to discharge at a linear rate (determined by the reference voltage). This discharge continues until the integrator voltage reaches the comparator trip point, which is referenced to the voltage on the Auto-Zero capacitor. When this level is reached, the comparator changes state, commanding the microcomputer to terminate the Read period. To facilitate auto-zero, the microcomputer then calls a reference voltage opposite in polarity to the one previously used (DE- or DE+). When the integrator reaches the trip point, the microcomputer immediately begins the Auto-Zero period.

3-26. The Integrate period (see Figure 4-4) starts on the leading edge of the integrate command from the microcomputer; switch Q21 is closed and switch Q7 is

opened. The RTD input voltage is applied through switch Q21 to the Buffer input. After a 1 ms settling period, switch Q7 closes, and the Buffer output is applied to the

Integrator for 100 ms. As the integrator capacitor C2 charges, the Integrator drives the comparator, through the gain stage to +5V dc which indicates that the charge on C2 is more negative than the Auto-Zero Reference Cl2. At the end of the Integrate period, the integrate capacitor is charged to a level and polarity proportional to the RTD voltage, and switches Q21 and Q7 return to the open state.

3-27. The Read period starts at the end of the Integrate period. Depending upon the input polarity sensed by the comparator during the Integrate period, one of two Read modes is enabled if a positive input is sensed, a positive

3-31. Offset voltages present during the Integrate and Read periods are cancelled by offset voltages that were sampled and held during the Auto-Zero period.

3-32. POWER SUPPLY

3-33. The 2190A Power Supply consists of a DC to DC

Converter and regulating circuitry. AC inputs are made via the input power cord, line fuse, and power transformer/rectifier. External +12V dc inputs can also be made directly to the DC to DC Converter circuitry via line TBl (see Main PCB schematic. Section 8). The function of the power supply is to provide +5V, +5V unregulated, +15V, and -15V dc operating voltages for the 2180A circuitry. The power supply can be driven from ac line or 12V dc external source. The DC to DC conversion and voltage regulation is accomplished using conventional power supply design techniques.

4-38. The following instructions provide a recommended method of constructing a ice bath:

NOTE

Distilled water must be used to make the ice and must also be used in the ice bath.

1. Required material; supply of ice, distilled water,

and an insulated jar with an unbreakable lid (thermos or equivalent).

2. Prepare the insulated jar by drilling one or more

holes just large enough to accept the RTD Probe or Probes.

3. Fill the insulated jar with shaved or crushed ice.

4. Fill the insulated jar with enough distilled water so that the ice becomes slush but not enough to float

the ice.

NOTE

As the ice melts, siphon off the excess water and add more ice. Allow about 5 to 10 minutes for the water to drop back to the freezing point.

Output

602-1. INTRODUCTION

602-2. The 21X0-002 Option is an analog and digital output unit. It provides either the2180A or2190A Model Digital Thermometers with a recording output for a permanent record when required. The option may be ordered with the unit for factory installation or is available as a kit for installation in the field.

602-3. The analog output is available on the rear panel at two flush banana jacks with the polarity indicated. The output is a scaled voltage source of 1 millivolt per degree of temperature, regardless of the temperature scale selected, with the polarity as read on the display. For example; a reading of 251° F would output +251 mV dc;

97.3°C would output +97.3 mV dc; and -31.9°F would output -31.9 mV dc.

602-4. The digital output is a clocked message that can be in two different formats to match the requirement of the customer’s equipment. Output on one set of lines is a bit-parallel, byte-serial message format designed for printer interface. Also available are the standard EIA RS232C and current loop bit-serial outputs. Both formats provide the channel number, the current reading displayed, and any out of range or open thermocouple information.

602-10. All connections between the Output Unit Option and external instruments are made using the rear panel connectors previously described. The analog output is from standard banana jacks. The digital output female connector has a mating male connector accompanying the option. This allows the customer to

custom make a cable between the thermometer output option and the receiving device. Table 602-3, is the pin out data for the digital output connector.

602-2

NOTE

Standard RS232C signals are output on 25-

pins, the connector on the -002 Output Option

is 36-pins, therefore, the user must either hardwire the connection between the -002 Output Option or order the Y2026B, Cable

Adapter,

602-11. OPERATION

NOTE

For RS232Cor20 mA current loop operation, the -002 address switches may be ignored.

The Data Set Ready (DSR, pin 33) or Clear To Send (CTS, pin 32)must be at +5 Vto +75 V

in order to output data on the RS232C bus.

These lines can be tied to Request To Send

(RTS), pin 31) which provides the required

+JSV.

602-12. Once the Output Unit Option is installed, the only operator functions deal with the connection of external equipment to the analog or digital output connectors.

602-13. The positive and negative analog terminals have available a dc millivolt output with the same polarity, and proportional to the temperature displayed. For example, if the thermometer displayed +105.7° F the analog output would be +105.7 mV dc and for -53.1°C the output would be -53.1 mV dc. The full resolution of the temperature display (tenths or hundredths of degrees) is reflected on the output.

602-14. The digital output can be connected to a printer or any device accepting parallel ASCII data, or to a device accepting RS232C or Current Loop signals. Connections for all three types of signals are available simultaneously on the 36-pin output connector previously described.

602-15. THEORY OF OPERATION

602-16. The Output Unit Option converts the temperature displayed by the output into a format usable by the customer’s equipment. The output may be available as a scaled analog voltage or as formatted parallel and serial ASCII digital output. The following paragraphs describe operation of the Accessory Bus that handles communication between the instrument and the options, the analog output circuitry and the digital output circuitry. Refer to the schematic in Section 8 during the following discussion.

602-17. Accessory Bus Communication

602-18. The option communicates with the thermometer on the clocked bit-serial accessory bus. Transmitted on the bus are channel number, range, conversion type, scale, and digits of the temperature reading. When the WRTADR line is held low, DCLK clocks the address of the Output Unit (4), followed by the thermometer data to the microprocessor on the DATA

line. Once into the microprocessor, the data is converted, formatted, and output to the analog and digital output circuitry.

602-19. Analog Circuitry

602-20. The temperature reading received by the

microcomputer is used to generate an integrate control signal, the length of which is proportional to the magnitude of the temperature reading. This signal is used to turn on (close) the FET switches Q6 and U12-2, open the switches Ull-2, U11-3 and U12-3, and set the output polarity with switches at U12-9 and U12-10. (U12-9 is closed when a negative reading is being processed and U12-10 when a positive signal is being processed.)

602-21. With Q6 on, the capacitor C1 is charged linearly to a voltage proportional to the length of the control signal at Q6. When Q6 has been on for the time required, it is opened, and switch U11-13 is closed, so the output of U13-8 can be sampled and held on C2. After 10 ms switch Ull-3 opens and switch Ull-11 closes to zero the integrate capacitor Cl, until the next conversion cycle.

602-22. The voltage held on C2 is buffered by U13-7. U13-14 either passes the voltage directly to the output stage, or amplifies it as controlled by switches U12-9 and U12-10, which alternate states to set the polarity. The output stage at U13-1 has a constant gain of -1.

602-23. Digital Output Circuitry

602-24. The thermometer reading transmitted on the accessory bus every 333 ms is formatted by the microcomputer and, if requested, made available on the PTI Bus, RS232C, and current loop outputs. Refer to the schematics in Section 8 during the following description.

602-25. Eight data, four address, a data valid, an address valid, and an acknowledge line are used by the PTI Bus Interface. The external device requests data from the Out put Unit by applying the preselected address to the address lines. The address is preselected by setting switch S3 to the

desired number (0-9). When the proper address is decoded

the tri-state output buffers (U8 and U9) are enabled, and

the microcomputer and external device are notified that the

Output Unit has a valid address. When the conversion pro

cess is complete, the microcomputer applies the first char

acter of the formatted data to the output lines and pulls the

DATVAL line low. The external device reads the data and pulls the ACK line low, causing the Output Unit to reply with a new character. The process is repeated until data transfer is complete. The message formats are shown in Figure 602-1, and a timing diagram is shown in Figure 602-2.

602-3

Page 56

21X0A-002

602-26. After transfer to the printer lines is complete, the microcomputer checks the DATA SET READY and CLEAR TO SEND lines from the RS232C Interface. If both lines are high, the same message as was output on the print lines is output on the RS232C and current loop lines in a bit-serial format. Since the thermometer cycle rate of 333 ms is shorter than the time required to output data at BAUD rate of 1200 and less, a message is not transmitted during every instrument cycle.

602-27. CALIBRATION

602-28. Analog circuitry in the option should be calibrated every 90 days or after any repair of the unit. The procedure following assumes that power is supplied to the unit and that a Digital Voltmeter capable of reading

10 mV on the 1 volt, or equivalent range, i.e., a Fluke

Model 8800A, is available.

1. Remove power from the instrument.

2. Remove the top cover from the thermometer.

3. Remove the screws attaching the option pcb to the Main PCB.

4. Leaving the interconnect cables connected, turn the option pcb to the right, while facing the instrument, exposing the component side and making the switches and adjustment accessible.

7. Set the FUNCTION switch (S2) to position I (CAL 1).

8. Adjust R26 for an output of 0 ± O.I mV dc.

9. Set the FUNCTION switch to position 2 (CAL

2).

10. Adjust R15 for an output of 0 ± 0.1 mV dc.

11. Set FUNCTION switch to position 3 (CAL 3).

12. Adjust R11 for an output of -lOV ± 1 mV dc.

13. Set FUNCTION switch to position 4 (CAL 4).

14. Adjust RI9 for an output of+I0V ± I mV dc.

15. Remove power and the test DMM, then reinstall the option pcb on the Main PCB and the

top cover on the instrument.

602-29. TROUBLESHOOTING

602-30. Troubleshooting for the 2180A Option -002, Output Unit, consists of the tabular flow chart in Table 602-4. When a step on the flow chart is completed, check for a decision transfer. If no decision is required, perform the next step of the table in sequence.

5. Connect the DMM to the Analog Output Connector.

6. Apply power to the instrument and allow if to warm-up for a minimum of 5 minutes.

Option -004

IEEE-488 Interface

604-1. INTRODUCTION

604-2. Option 21X0A-004 IEEE-488 Interface provides the 2180A and 2190A digital thermometers with a direct output only connection to the IEEE-488 bus.

604-3. Option 21X0A-004 may be ordered with the 2180A and 2190A thermometers for factory installation, or is available by itself for service center installation. Option 21XO A-004 cannot be used in a 2300A Scanner system. For more compatibility information, refer to “Compatibility With 2300A and Previously Produced Thermometers”.

604-4. The IEEE-488 standard connector is accessible from the rear panel of the thermometer. The format of the output data includes the channel number, the current read ing, and any out-of-range or open thermocouple informa tion. (Refer to Table 604-3.)

604-5. SPECIFICATIONS

604-6. Specifications for Option 21 XO A-004 are shown in

Table 604-1.

NOTE

The L4 listener function indicates that the

thermometer IEEE-488 bus interface has the

same 5-digit talk and listen addresses, and that

the receipt of a listen address disables the talk

address.

604-7. IEEE-488 BUS ADDRESS CODE

SELECTION

604-8. A six-position dip switch (SW3), located on Option 21X0A-004 pea (printed circuit assembly), sets the IEEE-488 bus address codes for the option. To gain access to SW3, lift off the case top of the thermometer by remov

ing the six screws from the base. Referring to Table 604-2, set positions 1 through 5 of SW3 to assign the desired address.

604-9. OPERATION

604-10. Once Option 21X0A-004 is installed and SW3 is

properly set, make sure that the IEEE-488 cable is correctly

connected to the option to ensure that all functions are

properly monitored by the controller.

604-11. Program Considerations

604-12. Position 6 on SW3 controls the SRQ signal (Ser vice Request) to the IEEE-488 bus. Upon receiving an

SRQ, the controller serially polls each device on the bus for

SRQ status. SRQ status of the Option 21X0A-004 is indi cated by bit DB6 (position 64 decimal, 40 hexadecimal) in the serial poll register (U12). With SW3 position 6 in the ON position, SRQ is generated when a LF (line feed) is received in the 32-byte buffer of Option 21X0A-004. The

LF character is used by the thermometer to indicate the end of a data transfer to the Option 21 XO A-004. (Refer to Table 604-3.) Option 21X0A-004 sets DBl (2 decimal), which causes a serial poll to return a total value of decimal 66 or 42 hexadecimal.

604-13. When the SRQ mode is enabled, the SRQ is set

when the thermometer makes a reading available to the

Option 21X0A-004. The reading is held indefinitely until

the SRQ is serviced. All new readings from the thermom eter are discarded. When SRQ is disabled, the output

buffer is continuously updated with the most recent reading from the thermometer. However, there may be a 0.33 second delay encountered in the returned reading. This delay occurs when one reading is sent across the IEEE bus

and the Option 21X0A-004 waits for the thermometer to send the next reading. An IEEE bus timeout error may occur unless the timeout is set longer than this delay.

604-15. Table 604-3. contains the sequence of information in the output data string. The sequence is the fixed length

format presented on the IEEE bus.

604-16. Sample Programs

604-17. The following sample programs show two differ ent situations in which the controller receives temperature readings from the thermometer. The program listed in Fig ure 604-1 instructs the controller to asynchronously retrieve a temperature reading after an SRQ has been sent from the thermometer. The program listed in Figure 604-2 instructs the controller to ask for a temperature reading at a specific program step.

604-18. SRQ Program

604-19. The SRQ program, when typed into a 1720A,

1722A, or 1752A controller informs the controller what to do when an SRQ is received from the thermometer. The program allows the controller to perform other tasks until the thermometer has a temperature reading. The thermom eter sends a 66 hexadecimal value back to the controller in response to the serial poll (SPL). If more than one ther mometer or more than one other instrument (a maximum of 14) is connected to the controller, the program distin

guishes which instrument is sending the SRQ and deter

100, 200, 220, 240V ac ± 10% 50/60 Hz, 3VA. (The 12-volt battery operation is not supported.)

mines priority if more than one SRQ is received at the same time. After the controller receives the temperature reading and prints it on the controller screen, the program ends the

SRQ handling procedure and waits for another SRQ.

NOTE

The following programs are written in Fluke BASIC and operate on the 1720A, 1722A, and 1752A controllers. A modification of the SRQ

program may be required to conform to other

IEEE controllers.

604-20. The Non-SRQ Program

604-21. The sample program in Figure 604-2 inputs and prints temperature readings without the use of an SRQ. A 2-second delay is required after the TRIG @2 statement (line 50) to allow Option 21X0A-004 to finish the reset pro cess before requesting readings from it. The TIMEOUT delay (line 70) must be set greater than 333 ms, so the con troller waits for the thermometer to provide the next read ing to the INPUT statement.

604-22. Group Execute Trigger

604-23. The Option 21X0A-004 responds to the IEEE488 GET command by simply resetting the two micropi ^cessors (U5 and Ull) on the board. Resetting the microp-

rocessors ensures that they are synchronized properly with the IEEE-488 interface chip (U12), and is a recommended start-up procedure at the beginning of the program in the IEEE-488 controller. A 2 second time delay is required to complete the resetting operation. Do not attempt to access Option 21X0A-004 before the end of the time delay.

604-24. Functional Equivalent

604-25. The operation of Option 21XOA-004 is functionally equivalent to the combination of the Fluke 21X0A-002, 2XXXA-522, and I120A with the exception of the follow ing four items:

CHANGES:

1. Option 21X0A-004 displays a lower case (d) instead of a blank in front of the temperature scale indicator. See Output Format, Table 604-3.

2. Option 21XO A-004 operates at the full speed rate of the thermometer, (3 readings per second, instead of 1.5 readings per second).

3. The 2XXXA-522 previously contained a bufferfull SRQ function that produced an SRQ when the 32-byte buffer is filled. The buffer-full SRQ function no longer exists with the 2XXXA-522, but the switch is still present and its function is still listed in the 2XXXA-522 manual. The buffer-full SRQ function is not available on Option 21X0A-004.

ADDED FEATURE:

(DCLK-) clocks the accessory bus address then the ther mometer data into the 3870 microprocessor (U5) on the DATA- line. In U5, the data is formatted (Table 604-2) and made available for transfer to the 8748 microprocessor (Ull).

604-29. U5 applies a character to the tri-state buffers (U8 and U9) and pulls the Data Valid (DATVAL) line low. If Ull is not transferring data to UI2 or if it is waiting for SRQ to be serviced, Ull responds to U5 by strobing the character onto the Option Data Bus with a STROBE- sig

nal and reads the character into its 32-byte buffer. U11 also generates Acknowledge (ACK), which causes U5 to reply with a new character. When an LF character is detected, Ull unmasks the byte-out interrupt. If the SRQ switch is set to ON, the SRQ switch triggers the GPIA (General Purpose Interface Adapter) to send SRQ to the controller. The 32-byte buffer never completely fills because ther mometer readings consist of 21 bytes.

604-30. The IEEE-488 Bus Controller initiates the talk

mode by sending the talk address to the GPIA (U12) over

the IEEE-488 bus when Attention (ATN) is asserted true

low. The GPIA responds by setting the byte-out interrupt

(U12-40) high, as a signal to U11 to pass data bytes to U12. The following three conditions must be met before data transfer can begin:

® Ready For Data (RFD) from the IEEE-488 bus

is true (low).

• Data Accepted (DAC) from the IEEE-488 bus is false (high).

® Ull must have the byte-out interrupt unmasked.

4. Option 21 XO A-004 responds to a Group Execute Trigger. See Group Execute Trigger, paragraph 604-23.

604-26. If you include Option 21X0A-004 when up grading or adding new equipment to a system currently operating with the 21X0A-002, 2XXXA-522, or 1120A combination, note the first two changes listed in paragraph 604-25.

604-27. THEORY OF OPERATION

604-28. Option 21X0A-004 converts the temperature dis played by the thermometer into a format usable by an IEEE-488 Bus Controller. Option 21X0A-004 communi cates with the thermometer on the clocked bit-serial acces sory bus. The channel number, range, conversion type, scale, and digits of the temperature reading are transmitted on the bus. The cycle is repeated every 333 ms. When the Write Address (WRTADR-) line is held low. Data Clock

604-31. When the above conditions are met, UII sends the data byte to the Data Out Register of the GPIA via the Option Data Bus. At this time, the byte-out interrupt is set to zero, and the data byte is checked for the LF character. The GPIA handshakes the data byte to the IEEE-488 Bus, and the byte-out interrupt (U12-40), transmitted to UT1, is set to 1. If the data byte is an LF character, EOI (End or Identify) is also sent to the IEEE Controller to signal the end of a data reading. This process continues as long as there is data in the 32-byte buffer of U11. When the 32-byte buffer is empty, Ull masks the byte-out interrupt from the GPIA.

604-32. The IEEE-488 address setting for Option 21XOA004 is read by the GPIA (U12) via the Option 21X0A-004 data bus when the GPIA sends a strobe out on U12-4 to the address switch tri-state buffers (U18).

604-33. When the GPIA detects a Group Execute Trigger

for its address, it sets U12-24 to a logic high to cause a

604-5

Page 72

21XOA-004

Power On Reset (POR) via Q4 and U16. The POR resets U5 and Ull, and lasts for approximately 150 ms.

604-34. The power supply for Option 21XOA-004 power supply is a standard linear regulator using a full-wave center tap rectifier and pass transistor regulator (Q5). The regulator is driven by U17 and Q6, and is referenced from a

2.5-volt band gap reference (U15). U16 performs POR and low voltage detection. The option provides its own power rather than using the power supply of the thermometer, which is unable to provide enough additional power.

604-35. Option 21X0A-004 is a consolidation of the cir

cuitry from Option 21X0A-002, Option 2XXXA-522, and

1120A that is required for IEEE-488 output operation. The

consolidated circuitry does not include analog output cap

ability or the slow serial communication link between the Option 21X0A-002 and 2XXXA-522 microprocessors.

Instead, the circuitry uses the PTI (Portable Test Instru ment) parallel output port of the Option 21X0A-002 to communicate with the Option 2XXX A-522 microprocessor.

604-36. COMPATIBILITY WITH 2300A

AND PREVIOUSLY PRODUCED

THERMOMETERS

604-37. Option 21X0A-004 is not intended to be used with a thermometer that is a part of a 2300A Scanning Sys tem. In a 2300A system, an Option 2300A-005 or Option 2300A-006 should be installed in the 2300A for connection to the IEEE-488 bus. Option 2300A-005 is for output only, similar to Option 21X0A-004 operation. Option 2300A-006 additionally provides remote control of the 2300A. Options 2300A-005 and 2300A-006 use the 2XXX A-522 and 1120A for connection to the IEEE bus.

CAUTION

“2190”, the thermometer is an early version. Newer versions

begin with “800” or “900.”

604-39. If your thermometer is an early version, either of

the following two modifications may be performed:

1. The microprocessor in the thermometer can be replaced with a newer version. Contact your local

John Fluke Service Center to order the latest 2180A or 2190A standard versions.

a. When you are updating a 2180A to the latest

version, be aware there are changes in the avail able choice of Resistance Temperature Detec tor (RTD) linearizations. If you require the original linearizations, order a special retrofit kit Model 2180A/AYK. (P/N 796953)

b. When you are selecting from the latest versions

of 2190A linearizations, be aware that an enhanced microprocessor retrofit kit is also

available. The enhanced retrofit kit provides 15 thermocouple types. Order Model 2190A/ AMK (P/N 763292)

2. A modification to Option 21X0A-004 may alter natively be performed. Contact your local John

Fluke Service Center and arrange for the installa tion of a 2180A-4021W (JF P/N 539288) onto Option 21X0A-004. QI and Q3 are removed from the pea and replaced by the modification circuit. This modification makes Option 21X0A-004 compatible with all versions of 2180A and 2190A thermometers. A +5 volt connection is provided next to U2 to provide power to the added modifi cation circuit.

Option 21X0A-004 is not compatible with a 2300A Scanning System. Such use may cause channel numbers to be displaced by one read-

ing, and each reading may be output twice.

604-38. Option 21X0A-004 is not directly compatible with the earliest version of the 2180 A and 2190A thermome ters. A choice of either of the two modifications described below provides compatibility. To identify the early version of thermometer, observe the thermometer display as it is turned on. If the display characters begin with “2180” or

604-6

604-40. PERFORMANCE TEST

604-41. There are no adjustments or calibration.

604-42. With Option 21X0A-004 attached to a 2180A or 2190A thermometer, apply proper ac input voltage and measure for 5.05 ± O.I volts dc across TPl and TP2.

604-43. Connect Option 21XOA-004 to an IEEE-488 con

troller via the IEEE-488 bus. Execute the SRQ program in

Figure 604-1 to retrieve readings from Option 21X0A-004.

Limits

606-1. INTRODUCTION

606-2. The 21X0-006 Limits Option gives the 2180A

and 2190A Digital Thermometers the capability of providing both visual and electrical indications (alarms) when the temperature measurement exceeds either of a pair of selectable maximum/minimum limit values. Also selectable are, all for a single point, the delta function (displays the difference between the preset value and the temperature read), and the maximum/minimum display function (the highest or lowest temperature read since the last reset by the INITIALIZE MAX/MIN switch).

606-3. The Limits Option is available as factory

installed with initial order or may be ordered as a field

installable kit for addition to the instrument.

606-4. SPECIFICATIONS

606-5. Specifications for the Limits Option, 21X0-006, are as listed in Table 606-1.

WARNING

HAZARDOUS VOLTAGES MAY BE PRESENT WITHIN THE INSTRUMENT. ONLY QUALIFIED PERSONNEL SHOULD PERFORM THIS INSTALLATION PRO CEDURE.

1. Disconnect the thermometer from all power

sources.

2. Remove the screws on the bottom of the case that fasten the top and bottom of the PTI case together and remove the top half of the case.

3. Remove the hole plugs from the Limits section of the front panel and attach the standoffs supplied with the option to the front panel.

4. Position the Limits PCB so that the thumbwheel LED and pushbutton switch line up with the applicable front panel ports.

5. Attach the Limits PCB to the Main PCB using the screws supplied with the option.

6. Connect the cable on the Limits PCB to J4 on the Main PCB.

7. Replace the PTI cover on the instrument and reconnect to input power sources, if required, at this time.

606-8. OPERATING NOTES

606-6. INSTALLATION

606-7. Options for field installation can be installed using the following procedure:

606-9. Installation of the Limits Option enables the low current single contact relay (Kl) on the thermometer Main PCB. The contact points are available on a rear panel connector block.

606-1

Page 76

21XOA-006

NOTE

Once installed, there are no provisions for disabling the Limits Option. If a temperature display is desired without the relay or LED

indications, select one of the Limits functions

f> or and the maximum setting on the

numeric thumbwheel switches.

606-10. OPERATION

606-11. The position and general description of the Limits Option front panel controls is given in Section 2. A more detailed description of the three functions is given in the following paragraphs. The term "thermocouple" = "RTD" for the 2180A.

606-12. Limits Function

606-13. The Limits function is enabled when the function portion of the thumbwheel is set in either the ^ or > position. The front panel LED illuminates and the rear panel relay contacts close when either of the preset conditions are met. In the greater than (>) function the indications (LED and relay contacts) result from any temperature reading that exceeds the value set on the limits thumbwheels. The less than (^) function gives its indication when the temperature read by the thermometer is equal to, or less than, the value set on the limits thumbwheels. The thumbwheel LSD is a whole number, fractional entries cannot be made.

606-14. Delta Function

606-15. When the Delta (A) function is selected on the thumbwheel the thermometer display reads the difference between the temperature at the thermocouple and the whole number setting of the thumbwheels. The formula used for the computation is:

606-18. THEORY OF OPERATION

606-19. The -006 Option supplies the thermometer with the function and numeric data selected on the front panel mechanical thumbwheel switches. When a Limits

function is selected, the data is stored for comparison on the option pcb. All communication between the option and the thermometer is done on the clocked serial accessory bus. This bus transmits and receives addresses, thumbwheel data, reset data, and limit status. Refer to the schematic in Section 8 during the Theory of Operation discussion.

606-20. Addressing

606-21. Each of the options on the bus is addressed with a different code. The thermometer uses the address "6" to talk to the Limits Option. To talk to any option the WRTADR (P4-3) line must be brought low, with WRT

(P4-4) high, followed by the applicable four address bits applied to the DATA (P4-5) line in succession, toggling DCLK (P4-6) for each bit. This clocks the address into the shift register (U2-15) where it is compared to the Limits Option address and, if valid, (U1-1 low) enables the gates required to shift data to the thermometer (U5-11) and into the Limits Option (U5-2). Details of the data transfer are in subsequent paragraphs.

606-22. Limits Option Outputs

606-23. Before the thermometer can input data from the

Limits Option, the Limits circuitry must be addressed as described previously (Ul-1 low). Once addressed the WRTADR and WRT lines go high. The low to high transition of WRTADR (U3-6) loads the shift registers from the thumbwheels and RESET switches. The two lines enable the output data line (Ul-13) and as the thermometer accepts the data it clocks the serial output shift registers with DCLK, transferring the data from the shift register to the thermometer.

T displayed = T at thermocouple - T thumbwheel setting (in degrees)

606-16. MINIMUM/MAXIMUM Display Function

606-17. The microcomputer acculmulates and stores the highest and lowest temperatures recorded since the last reset. When the Maximum (T) function is selected the highest temperature recorded and stored in the microcomputer is displayed. Selection of the Minimum function (i) displays the lowest recorded temperature since the last reset. To record the current temperature for either function, select the applicable function and depress the front panel reset switch.

606-2

606-24. In the thermometer the data is processed by the microcomputer to perform the proper action. For the Limits function the output is compared to the state of the limits and, if exceeded, the indicator illuminated and the relay energized. For the Delta function the temperature is compared against the transmitted value and the difference displayed. If either the Maximum or Minimum function is selected the stored value is displayed, but, in addition, the status of the RESET switch is checked.

606-25. Limits Option Inputs

606-26. The thermometer transmits to the Limits Option only the Limits Exceeded status. After the option has been addressed (Ul-1) WRTADR goes high to

Page 77

21X0A-006

disable the addressing circuit (U4-13) while WRT stays low to enable the Limits Exceeded input (U5-8) so that DCLK can clock the data into the latch (U5-1). A Limits Exceeded indication clocks a high into the latch resulting in a low at the output (U6-12) to turn on CRl. The limit not exceeded or another function selected, loads a low into the latch to turn off the indicator.

606-27. CALIBRATION

606-28. The Limits Option has no variable components and does not require calibration.
