General
The Model 1057 is easy to wire. It includes removable connectors and slide-out signal input boards.
Removable Connectors and Signal Input Boards
Model 1057 uses removable signal input boards and communication boards for ease of wiring and installation. Each of the signal input boards can be partially or completely removed from the enclosure for wiring. The Model 1057 has three slots for placement of up to three signal input boards and one communication board.

3.1.3
Section 3: Wiring
Note: If the UL option code has been ordered, a plastic insulator shield surrounds the entire power supply board (AC power supply only). The protective insulator shield does not appear in this photo.
Signal Input Boards
Slots 1, 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement board following the lead locations marked on the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a sealed enclosure.
Note: that signal input board 3 is inserted into slot 1. Board 3 is inverted in the slot to allow board components to face to the right. Board 3 uses a long ribbon cable to connect to the main PCB. Boards
1 and 2 use a split ribbon cable to connect both signal boards to a common connector on the main board.
Alarm Relays
Four alarm relays are supplied with the switching power supply (84 to 265 Vac, 03 order code) and the 24 Vdc power supply (20-30 Vdc, 02 order code). All relays can be used for process measure ments or temperature. Any relay can be configured as a fault alarm instead of a process alarm.
Each relay can be configured independently and each can be programmed as an interval timer, typically used to activate pumps or control valves. As process alarms, alarm logic (high or low acti vation or USP*) and deadband are user-programmable. Customer-defined failsafe operation is supported as a programmable menu function to allow all relays to be energized or not-energized as a default condition upon powering the analyzer. The USP alarm can be programmed to activate when the conductivity is within a user-selectable percentage of the limit. USP alarming is available only when a contacting conductivity measurement board is installed.

Section 3: Wiring
Sensor Wiring to Signal Boards
Wire the correct sensor leads to the measurement board using the lead locations marked directly on the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland.
For best EMI/RFI protection use shielded output signal cable enclosed in an earth-grounded metal conduit. Connect the shield to earth ground. AC wiring should be 14 gauge or greater. Provide a switch or breaker to disconnect the analyzer from the main power supply. Install the switch or breaker near the analyzer and label it as the disconnecting device for the analyzer. Keep sensor and output signal wiring separate from power wiring. Do not run sensor and power wiring in the same conduit or close together in a cable tray.

Configuring and Ranging The Current Outputs
Purpose
The Model 1057 accepts inputs from three sensors and has four analog current outputs. Ranging the outputs means assigning values to the low (0 or 4 mA) and high (20 mA) outputs. This section provides a guide for configuring and ranging the outputs. Always configure the outputs first.
Definitions
1. Current ouputs - The analyzer provides a continuous output current (4-20 mA or 0-20 mA) directly proportional to the process variable or temperature. The low and high current outputs can be set to any value.
2. Assigning outputs - Assign a measurement to outputs 1, 2, 3, or 4.
3. Dampen - Output dampening smooths out noisy readings. It also increases the response time of the output. Output dampening does not affect the response time of the display.
4. Mode - The current output can be made directly proportional to the displayed value (linear mode) or directly proportional to the common logarithm of the displayed value (log mode).

Calibration - Introduction
Calibration is the process of adjusting or standardizing the analyzer to a lab test or a calibrated laboratory instrument, or standardizing to some known reference (such as a commercial buffer).
The auto-recognition feature of the analyzer will enable the appropriate calibration screens to allow calibration for any single sensor configuration or dual sensor configuration of the analyzer.
Completion of Quick Start upon first power up enables live measurements but does not ensure accurate readings in the lab or in process. Calibration should be performed with each attached sensor to ensure accurate, repeatable readings. This section covers the following programming and configuration functions:
1. Auto buffer cal for pH (pH Cal - Section 7.2
2. Manual buffer cal for pH (pH Cal - Section 7.2
3. Set calibration stabilization criteria for pH (pH Cal - Section 7.2
4. Standardization calibration (1-point) for pH, ORP and Redox (pH Cal - Section 7.2
5. Entering the cell constant of a conductivity sensor (Conductivity Cal - Section 7.4
6. Calibrating the sensor in a conductivity standard (Conductivity Cal - Section 7.4
7. Calibrating the analyzer to a laboratory instrument (Conductivity Cal - Section 7.4
8. Enter a manual reference temperature for temperature compensation of the process measure ment

pH Calibration
7.2.1 Description
New sensors must be calibrated before use. Regular recalibration is also necessary. Use auto calibration instead of manual calibration. Auto calibration avoids common pitfalls and reduces errors.
The analyzer recognizes the buffers and uses temperature-corrected pH values in the calibration.
Once the Model 1057 successfully completes the calibration, it calculates and displays the calibration slope and offset. The slope is reported as the slope at 25 °C. This section describes how to calibrate the model 1057 with a ph sensor. the following cali-

The pH measured by the Model 1057 analyzer can be changed to match the reading from a second or referee instrument. The process of making the two readings agree is called standardization. During standardization, the difference between the two pH values is converted to the equivalent volt age. The voltage, called the reference offset, is added to all subsequent measured cell voltages before they are converted to pH. If a standardized sensor is placed in a buffer solution, the measured pH will differ from the buffer pH by an amount equivalent to the standardization offset.

Contacting Conductivity Calibration
Description
This section describes how to calibrate a Model 1057 with Contacting Conductivity Sensor attached.
Placing A New Conductivity Sensor In Service
New conductivity sensors rarely need calibration. The cell constant printed on the label is sufficiently accurate for most applications.
Calibrating An In-Service Conductivity Sensor
After a conductivity sensor has been in service for a period of time, recalibration may be necessary.
There are three ways to calibrate a sensor.
1.
Use a standard instrument and sensor to measure the conductivity of the process stream. It is not necessary to remove the sensor from the process piping. The temperature correction used by the standard instrument may not exactly match the temperature correction used by the Model 1057. To avoid errors, turn off temperature correction in both the analyzer and the standard instrument.
2.
Place the sensor in a solution of known conductivity and make the analyzer reading match the conductivity of the standard solution. Use this method if the sensor can be easily removed from the process piping and a standard is available. Be careful using standard solu tions having conductivity less than 100 µS/cm. Low conductivity standards are highly sus ceptible to atmospheric contamination. Avoid calibrating sensors with 0.01/cm cell con stants against conductivity standards having conductivity greater than 100 µS/cm. The resistance of these solutions may be too low for an accurate measurement. Calibrate sen sors with 0.01/cm cell constant using method 3.
3.
To calibrate a 0.01/cm sensor, check it against a standard instrument and 0.01/cm sensor while both sensors are measuring water having a conductivity between 5 and 10 µS/cm. To avoid drift caused by absorption of atmospheric carbon dioxide, saturate the sample with air before making the measurements.
To ensure adequate flow past the sensor during calibration, take the sample downstream from the sensor. For best results, use a flow-through standard cell. If the process temperature is much different from ambient, keep connecting lines short and insulate the flow cell.

Calibrating The Sensor In A Conductivity Standard (In Process Cal)
This procedure is used to calibrate the sensor and analyzer against a solution of known conductivity.
This is done by submerging the probe in the sample of known conductivity, then adjusting the dis played value, if necessary, to correspond to the conductivity value of the sample. Turn temperature correction off and use the conductivity of the standard. Use a calibrated thermometer to measure temperature. The probe must be cleaned before performing this procedure.
