Introduction

1.2 SAFETY CONSIDERATIONS

This device is marked with the international caution symbol. It is important to read this manual before installing or commissioning this device as it contains

important information relating to Safety and EMC (Electromagnetic Compatibility).

This instrument is a panel mount device protected in accordance with EN 610101:2001, electrical safety requirements for electrical equipment for measurement, control and laboratory. Installation of this instrument should be done by qualified personnel. In order to ensure safe operation, the following instructions should be followed.

This instrument has no power-on switch. An external switch or circuit-breaker shall be included in the building installation as a disconnecting device. It shall be marked to indicate this function, and it shall be in close proximity to the equipment within easy reach of the operator. The switch or circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it shall meet the relevant requirements of IEC 947–1 and IEC 947-3 (International Electrotechnical Commission). The switch shall not be incorporated in the main supply cord.

Furthermore, to provide protection against excessive energy being drawn from the main supply in case of a fault in the equipment, an overcurrent protection device shall be installed.

• Do not exceed voltage rating on the label located on the top of the instrument housing.

• Always disconnect power before changing signal and power connections.

• Do not use this instrument on a work bench without its case for safety reasons.

• Do not operate this instrument in flammable or explosive atmospheres.

• Do not expose this instrument to rain or moisture.

• Unit mounting should allow for adequate ventilation to ensure instrument does not exceed operating temperature rating.

• Use electrical wires with adequate size to handle mechanical strain and power requirements. Install without exposing bare wire outside the connector to minimize electrical shock hazards.

EMC Considerations

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems persist.

Failure to follow all instructions and warnings may result in injury!

About The Meter

2.7 DISASSEMBLY

You may need to open up the meter for one of the following reasons:

• To check or change the 115 or 230 Vac power jumpers.

• To install or remove jumpers on the main board.

Disconnect the power supply before proceeding.

To remove and access the main board, follow these steps:

• Disconnect the main power from the meter.

• Remove the back case cover.

• Lift the back of the main board upwards and let it slide out of the case.

Getting Started

SECTION 3. GETTING STARTED

Caution: The meter has no power-on switch, so it will be in operation as

soon you apply power.

If you power off/on the meter, or perform a hard reset (press the RESET button twice), the meter shows “RST”, followed by "ORP".

3.1 RATING/PRODUCT LABEL

This label is located on top of the meter housing (refer to Figure 3-4).

3.2 MAIN BOARD POWER JUMPERS (refer to Figure 3-1)

Important: If you want to change the Factory preset jumpers, do the

following steps; otherwise go to section 3.3.

Disconnect the power from the unit before proceeding.

1. Remove the main board from the case. Refer to Section 2.7.

2. Locate the solder jumpers W1, W2, and W3 (located near the edge of the main board alongside the transformer).

3. If your power requirement is 115 V ac, solder jumpers W1 and W3 should be

wired, but jumper W2 should not. If your power requirement is 230 V ac, solder jumper W2 should be wired, but jumpers W1 and W3 should not.

Figure 3-1 shows the location of solder jumpers W1 through W3.

3.3 MAIN BOARD JUMPERS (Continued)

S1 and S2 jumpers are for factory use only.

Do not install or remove them, as reading errors may result

S3 jumpers are used for the following: (Refer to Figure 3-2)

* To enable or disable the front panel push-buttons * To allow for an extremely low resistance load for analog output * To disable the MENU button * To perform calibration procedure

Configuring The Meter

2020

SECTION 4. CONFIGURING THE METER

• Refer to Table 7-1 for a summary list of menu configuration.

• Factory defaults are in bold and italics.

4.1 Configuring Decimal Point ("DEC.P")

Under this menu there are two choices:

FFFF. The meter's resolution is configured for mV - default.

FFF.F The meter's resolution is configured for 0.1 mV.

1. Press the RAW/mV button once, the current decimal point resolution is displayed.

2. Press the



/ORP button to select the desired resolution, then press the Menu button to store this value. The "STRD" momentarily appears then the next menu will automatically appear on the display.

Setpoint value and deadband’s decimal points are automatically updated when you change the decimal point. If any of these values are overflowed, then the meter will flash "ER 2", momentarily warning that one of these values has been corrupted. Then go to the next menu. New decimal point will be substituted.

4.2 Using Reading Configuration ("RD.CF")

Under this menu there is 1 submenu and 2 choices for the submenu:

R.1=F For filtered ORP values - default.

R.1=U For unfiltered values.

1. Press the RAW/mV button once. R.1=F or R.1=U will flash.

2. Press the



/ORP button to select desired choice.

3. Press the MENU button to store this value. The "STRD" momentarily displays, followed by "CAL.2".

1. Immerse the ORP probe in a known solution (low point).

2. Press the MENU button until "CAL.2" displays.

3. Press the /RAW mVbutton. "IN 1" (input 1) displays.

4. Press the RAW/mV button again. The last input 1 stored value displays with the fourth digit flashing.

5. Press the RAW/mV button once more. Actual signal being received by your meter displays with no flashing digits.

6. Press the MENU button to store this value as "IN 1" (input 1).

7. "RD 1" displays.

8. Press the RAW/mV button. The last "RD 1" value stored displays with the fourth digit flashing.

9. Press the



/ORP button to change the value of your digits.

10.Press the RAW/mV button to scroll horizontally to the next digit.

11.Press the MENU button to store value as "RD 1". "IN 2" (input 2) displays.

12.Immerse the ORP probe in the next solution (high point) and wait for it to settle.
