TEMP / HUMIDITY TRANSDUCER

Inspect the package for damage. If damaged, notify the appropriate

carrier immediately. If undamaged, open the package and inspect

the device for obvious damage. Return damaged products.

• Do not use on oxygen service, in an explosive/hazardous

environment, or with flammable/combustible media.

• Disconnect power supply before installation to prevent

electrical shock and equipment damage.

• Make all connections in accordance with the job wiring diagram

and in accordance with national and local electrical codes. Use

copper conductors only.

• Use electrostatic discharge precautions (e.g., use of wrist straps)

during installation and wiring to prevent equipment damage.

• Avoid locations where severe shock or vibration, excessive

moisture or corrosive fumes are present. NEMA Type 4 housings

are intended for outdoor use primarily to provide a degree of

protection against wind-blown dust, rain, and hose-directed water.

• Do not exceed ratings of the device.

• Tools (not provided)

- Digital Volt-ohm Meter (DVM)

- Appropriate screwdriver for mounting screws

- Appropriate drill and drill bit for mounting screws

• Appropriate accessories

• Two #8 self-tapping mounting screws (not provided)

• Training: Installer must be a qualified, experienced technician

CHECKOUT DIMENSIONAL DATA

CALIBRATION

1. Verify that the unit is mounted in the correct position.

2. Verify appropriate input signal and supply voltage.

3. Verify appropriate configuration range.

CAUTION: Never connect 120 VAC to these transducers.

Never connect AC voltage to a unit intended for DC supply.

Transducer

Operation

Calibration of HU-226 mA/VDC Humidity Transducer

Field calibration instructions are provided with the following

precautions and advice:

1. Do not verify comparative RH with a sling Psychrometer.

There are far too many variables which induce errors into

this process. New HU-226 RH transducers are already

supplied with calibration.

2. Recalibration must be done in a controlled environment.

Relative humidity must be held stable while making any

adjustment.

3. Verify the output from the device directly with calibrated

instrumentation and verify the RH with calibrated instrumen-

tation, (NOT A CONTROLLER OUTPUT). With the correct

power applied and only a meter connected to the output of

the transducer, ensure that the output is proportional to the

true RH.

4. A) SINGLE POINT CALIBRATION:

[NOTE: SELECT EITHER OPTION 1 OR OPTION 2,

BUT NOT BOTH.]

Option 1. Select a controlled humidity environment

between 10 & 40% R.H. Insure humidity

is stable and adjust zero trimmer (Z).

Option 2. Select a controlled humidity environment

between 40 & 70% R.H. Insure humidity

is stable and adjust span trimmer (S).

B) TWO-POINT CALIBRATION: Select a controlled

humidity environment between 10 & 40% RH Insure

humidity is stable and adjust zero trimmer (Z). Then

select a controlled humidity environment between

70 & 75% RH. Insure humidity is stable and then

adjust span trimmer (S).

All units are factory calibrated to meet or exceed published

specifications. If field adjustment is necessary, follow the

instructions below.

MAINTENANCE

Regular maintenance of the total system is recommended to

assure sustained optimum performance.

FIELD REPAIR

None. Replace with a functional unit.

WARRANTY

See Data Sheet for additional information.
