Chapter 4: CALIBRATION

The calibration mode is accessible through the configuration menu or from the weigh mode.

Calibration Methods

There are six methods of calibration. Press > to select a calibration method. Press  to begin the

calibration method selected. Refer to the appropriate section for calibration instructions.

• New Zero - Establishes a new zero (no load) and span (test load) calibration reference.

• Last Zero - Performs a span re-calibration without removing the test load. (This selection is not

available with linearization enabled.)

• Temp Zero - Performs a calibration without removing the current gross weight. The zero reference determined during the last calibration is maintained. (This selection is not available with linearization enabled.)

• Only Zero - Establishes a new zero reference without affecting span.

• Cal Reset - Adjusts the zero and gain factors of the A/D amplifier to default values for

maximum sensitivity.

• Known LCOut - Calibrates without the use of test weights. The mV/V value and full scale capacity of each load cell must be known.

GENERAL NOTES ON CALIBRATION

Temporary Zero

Temp Zero is used to calibrate without establishing a new zero. Calibration can be performed without removing the currently applied gross load. A temporary zero is established so that test weights can be added during calibration. The original zero reference determined during the previous calibration is not affected. This procedure is commonly used to calibrate hopper scales where it is impractical to empty the product before calibrating.

Only Zero

Only Zero is used for zero calibration only. This calibration procedure is primarily used for the zero reference after changing a scale’s dead-load, such as adding safety rails to a scale deck or installing a mixer motor on a hopper scale. Because the full scale capacity is referenced from the last zero calibration, performing a zero calibration helps to ensure that the full scale over-load will not occur prematurely due to the additional dead-load.

Chapter 5: LEGAL FOR TRADE

The Model 675 default parameter setup does not ensure compliance with legal-for-trade installations as mandated by local weights and measures authorities. This chapter contains information on NTEP and OIML regulations, sealing and audit trails, and other requirements.

Since legal-for-trade requirements may vary, you must ensure that the Model 675 installed in accordance with all local regulations.

NTEP Requirements

The National Type Evaluation Program (NTEP) is a widely accepted weights and measures standard in the United States, with most states abiding by some or all of the NTEP requirements. A complete list of these regulations is available in the “Handbook 44” publication distributed by the National Institute of Standards and Technology (NIST). For more information, call (301) 975-3058, or visit http://www.nist.gov.



In order to configure the Model 675 to comply with NTEP requirements, parameter P440 (NTEP) must be enabled. This ensures the following:

The Model 675 NTEP Certificate of Conformance (C.O.C.) is 05-023A2.

Model 675 User’s Guide

NTEP Custom Setup

The “Custom Setup” parameter, P60205 of the information parameters, displays a list of parameters which, if configured improperly, could facilitate fraud in a legal-for-trade installation. A weights and measures inspector might check this parameter and inquire about the configuration of any parameters that appear in this list.

ACCESSING THE CUSTOM SETUP LIST

DO NOT ATTEMPT TO ACCESS THE CUSTOM SETUP LIST DURING CRITICAL WEIGHT PROCESSING! It is important to note that all functions of the operating mode will be suspended

immediately upon accessing the information parameters. This includes suspension of weight conversions, deactivation of all setpoints and cancellation of custom transmits. The “Custom Setup” list may be accessed from the weigh mode as shown in the example – Accessing the NTEP Custom Setup List. An access code is not required to view this list.

TO ACCESS THE CUSTOM SETUP LIST:

Sealing and Audit Trails

Most legal-for-trade installations will require the Model 675 to be sealed. A sealed indicator cannot be accessed for setup or calibration changes without breaking a physical seal or incrementing an event counter, thus providing evidence of tampering.

The Model 675 has two types of sealing provisions, a physical seal and a three event audit trail counter. Check with your local weights and measures authority to determine your requirements.

PHYSICAL SEAL

The most common sealing method is a lead-wire seal. The Model 675 provides an easy means of applying this type of seal as shown in Figure 9.

Before applying a wire seal, move the program jumper to.

1. Remove the two screws from the bottom plate nearest the back panel.

2. Move the program jumper E3 into the ‘NO’ position as shown in Figure 8. This will prevent access to

the Setup and Calibration Modes.

Page 41

Chapter 5

Figure 8: Program Jumper

3. Install both bottom plate screws. Make sure the screws have a hole to pass a lead seal through.

4. Pass the lead seal through the holes of both screws.

Figure 9: Lead Seal

AUDIT TRAILS

Three separate incrementing, non-resetable audit trail parameters are used by the Model 675 to indicate changes to various parameters, P60201 – OIML, P60203 – Calibration , and P60204 – Setup. An audit trail counter will increment only once upon exiting the Setup Mode and saving changes regardless of how many settings were changed.

Calibration Audit Trail

Any changes to the existing calibration will increment the Calibration (CAL) audit trail at P60203.

Setup Audit Trail

Changes to any of the Setup Mode parameters will increment the setup audit trail at P60204.

OMIL REQUIREMENTS

The International Organization of Legal Metrology is an inter-governmental body which harmonizes the national metrology regulations of its worldwide members. A list of regulation publications can be obtained from the Bureau International de Métrologie Légale (BIML) in Paris, France.

• An over-load condition will result when the gross weight exceeds nine (9) graduations

over the full scale capacity.

• Full scale capacity is always referenced from the last zero calibration reference, not the

last zero acquired by pressing

• Presettable parameters will give indication that a value has been entered manually.

Most NTEP requirements will also apply. See the NTEP section of this chapter for additional considerations.

Enabling OIML Operation

In order to configure the scale to comply with OIML requirements, P410 must be enabled in the setup mode (see Model 672/675 Technical Reference Manual for details). Doing this will ensure the following:

OPERATIONAL ERRORS

MESSAGE DESCRIPTION

Input signal less than negative full scale. If this is due to excessive loading, reduce the load. Otherwise check the load cell connections. If a 4 wire load cell cable is being used, check that the sense jumpers are in place. Verify that the capacity selection P110 is correct. Use the information parameters, especially P61103 and P61104, to check the setup and input signal.

Input signal is greater than positive full scale. Use same check as for underload.

load is always to be present, apply this dead-load during the No Load? prompt during calibration to permanently eliminate the offset.

Tare entry was greater than full scale. Most likely the entered tare value was incorrect.

Negative tare attempted, but not allowed per P162. For auto-tares, the GROSS Weight must be greater than zero unless P162 is changed to allow negative tares.

The signal into the A/D is greater than +/- 2 times the expected full scale signal. For example if the full scale capacity at P110 is 100, then the error message will be displayed at +/- 208 taking into consideration the 4% overload. This error usually indicates a defective or incorrectly wired load cell.

A programming operation was attempted when the program jumper is installed. Installation of this jumper will prohibit any programming changes.

setup mode at P202. This could also result if the baud rate (P200) or the number of data bits (P201) are incorrect. The ‘X’ in the error message represents the COMM port number on which the problem occurred.

An overrun error occurred where additional characters were received while the receive buffer was full. The additional characters will be lost. The ‘X’ in the error message represents the COMM port number on which the problem occurred.

The stop bit of a received character did not occur when it was expected. This could be the result of an incorrect baud rate (P200), incorrect number of data bits (P201), or incorrect parity setting (P202). The ‘X’ in the error message represents the COMM port number on which the problem occurred.

The Model 675 did not check it’s receive data register in time, thus missing a character. To prevent the problem, try reducing the baud rate (P200). The ‘X’ in the error message represents the COMM port number on which the problem occurred.

Associated with Modbus. This is selected at P205. This message indicates that a transmission out the specified port was attempted. This is not acceptable if the port is set for Modbus. The ‘X’ in the error message represents the COMM port number on which the problem occurred.

Occurs if a data transmission is held up for two seconds of more due to a deasserted handshake. Refer to the description of parameter P209 for more information.

Occurs if the

shown or if P209 is set for abort and the transmit buffer becomes full. Appear briefly when the handshake is re-asserted after the tx on hold

message occurs. Appears briefly after an attempt was made to put a byte in an invalid

comm port receive buffer. An invalid communication port number was specified.

K key is pressed when the tx on hold error message is
