1. Introduction The Martel PTC8010 Temperature Calibrator is a handheld, battery-operated instrument that measures and sources temperature parameters. The calibrator has the following features and functions: • A graphics display. The display can be used to source and measure resistance temperature detectors (RTDs), thermocouples, milli volts and resistance.
1.3 Safety information Symbols Used The following table lists the International Electrical Symbols. Some or all of these symbols may be used on the instrument or in this manual. Symbol Description AC (Alternating Current) AC-DC Battery CE Complies with European Union Directives Double Insulated Electric Shock Fuse...

[DONE] returns to home menu. Contrast is adjusted using the arrow options, which are available after choosing [CONTRAST]. NOTE: The PTC8010 calibrator offers a wide range contrast adjustment feature to accommodate operation in extreme temperatures. In certain cases making large changes in contrast may render the display difficult to read under normal conditions.

The parameter selection menu is called up when [CONFIG] is selected from the main menu. It contains the following options: [SELECT], [NEXT], and [DONE]. When the display is selected, a parameter will start to flash. Use the [SELECT] option to change the parameter, and the [NEXT] option to switch to another variable.
2.3 Cursor control / Setpoint control The output value can be controlled by the four cursor control arrows on the keypad. By pressing one of the arrows a cursor will be added to the display under the last digit of the output value.
3.3 Measuring Temperature TC IN TYPE K 3.3-1 Using Thermocouples CJ=24.9 °C CJC ON The calibrator supports the following thermocouple types: B, C, E, J, K, L, N, R, S, T, U, BP , and XK. The characteristics of all the 50.0 °C types are described in Specifications section.
Choose 2, 3, or 4-wire connection [2W, 3W, 4W]. (4-wire allows for the most precise measurement) Select RTD type from the sensor types. Attach RTD leads as shown in Figure 8. MEASURE/SOURCE MEASURE/SOURCE RTD IN 4W P100-385 100.00 Ω 0.0 °C MEASURE/SOURCE MENU LIGHT...
4.2 Using the Automatic Output Functions There are two automatic output functions, step and ramp. The selected function can be turned on and off using the Output Home Menu. The Automatic Output Function parameters can be set in the Auto Function Menu. Parameters include: 1.
MEASURE/SOURCE Figure 10. Connections for Outputting RTDs 4.4 Sourcing Ohms/RTDs To source an RTD, follow these steps: 1. Select the [CONFIG] option from the main menu, and choose [RTD] from the primary parameters. 2. Choose output [OUT] from the input/output control, and select RTD type from the sensor types.
Note: The calibrator simulates a 2-wire RTD. To connect 3- or 4-wire transmitter, use stacking cables, as shown in Figure 15. 4.4-1 Custom RTD A custom curve-fit PRT may be entered into the calibrator for sourcing and measuring. To do so follow these steps: Select the [CONFIG] option from the main menu.
1. Start Hyper Terminal (located in Accessories/Communications of the Windows Start menu) 2. Select New Connection. 3. For Name enter PTC8010. Select the serial port that the unit is connected to. 4. Enter the above information for port settings. 5. Select ASCII setup from File/Properties/Settings and mark these choices:...
5.2 Changing Between Remote and Local Operation There are three modes of operation of the calibrator, Local, Remote, and Remote with Lockout. Local mode is the default mode. Commands may be entered using the keypad on the unit or using a computer. In Remote mode the keypad is disabled, and commands may only be entered using a computer, but choosing [GO TO LOCAL] from the menu on the calibrator display will restore keypad operation.

Numbers that have up to 15 significant figures and exponents. For example: CPRT_COEFA? returns 3.908000E-03 Character Response Data (CRD) Data returned as keywords. For example: RTD_TYPE? returns PT385_10 Indefinite ASCII (IAD) Any ASCII characters followed by a terminator. For example: *IDN? returns MARTEL, PTC8010, 250, 1.00...

5.3-4 Calibrator Status Status registers, enable registers, and queues provide status information on the calibrator. Each status register and queue has a summary bit in the Serial Poll Status Byte. Enable registers generate summary bits in the Serial Poll Status Byte. The following is a list of registers and queues along with their function.
Page 21
Power On. Set to 1 if power was turned on and off before the Event Status Register was read. Command Error. Set to 1 when the calibrator receives an invalid command. Entering an unsupported RTD type may cause such an error. Execution Error.
5.4 Remote Commands and Error Codes The following tables list all commands, and their descriptions, that are accepted by the calibrator. Table 5: Common Commands Command Description *CLS *CLS (Clear status.) Clears the ESR, the error queue, and the RQS bit in the status byte. Terminates pending Operation Complete commands *ESE Loads a byte into the Event Status Enable register.

*IDN? Returns the manufacturer, model number, and firmware revision of the Calibrator. For example: *IDN? will return MARTEL, PTC8010, 250, 1.00 *OPC Enables the Operation Complete setting in the ESR. This setting makes it possible to check if an operations is complete after it has been initialized.

CPRT_COEFC This command is used for entering a custom RTD into the calibrator. The numeric value entered after the command will be set as the first coefficient of the polynomial used by the custom RTD. For example: CPRT_COEFC -5.8019E-12 enters -5.8019e-12 as coefficient A. CPRT_COEFC? Returns the number which was entered for the first coefficient of the polynomial used in the custom RTD.
Page 28
Returns the value for the resistance in custom RTD. The above example would return: 1.000000E+02, OHM FAULT? Returns the error code number of an error that has occurred. The command may be entered when the previous command did not do what it was meant to do. Refer to the Error Codes table for more information on error code numbers.

RTD_TYPE Sets the RTD type. The following is a list of RTD types they way they should be entered after the command: PT385_10; PT385_50; PT385_100; PT385_200; PT385_500; PT385_1000; PT392_100; PTJIS_100; Ni120; Cu10; Cu50; Cu100; YSI_400; OHMS; CUSTOM; For example: RTD_TYPE PT385_10 sets RTD type to Pt385-10 RTD_TYPE? Returns the RTD type.
