Calibration Procedure—ST Series

WARNING: The calibration procedure requires approximately

5 minutes to complete. If gas is not applied at the appropriate time, a calibration
failure may occur (refer to "Calibration Failure/Interruption" on page 11 for
specific information).

For accurate performance, calibrate sensors using 50% span of the specific gas
of concern. The concentration of gas, c orresponding to 100% of full scale, is
converted to a linear 4 to 2 0 mA output signal which can be powered from the
primary dc supply of the instrument. Power up the unit for at least 4 hours
BEFORE first calibration.

The following calibration procedure should be followed to ensure an accurate
correlation between the 4 to 20 mA output signal and the gas concentration.

SENSORS—Periodic Response Test

M

AINTAIN

We recommend the sensors be verified or calibrated every 3 months. A typical
response check involves the application of calibration gas to the sensor, then t he
observation of the response LEDs, analog output, display and external
monitoring equipment. Be sure to prevent unwanted response of external
monitoring devices and equipment during this procedure. If the response to
calibration gas is within its specified accuracy then it is not necessary
perform

a calibration. For example, when 50% of full scale is applied, the

to

response is expected to be between 11.5 mA (47% of full scale) and 12.5 mA
(53% of full scale). An additional consideration is the accuracy tolerance of the
calibration gas which may be + or - a few percent. If t he calibration gas is + or ­10% of full scale then the reading may be from 10.7 mA (42% of full scale) to

13.3 mA (58% of full scale).

T

RO U B L E SH O OT

- Response to the input should be checked and, if necessary, calibration should
be performed whenever any of the following occur. Refer to "Calibration" on
page 10 for calibration instructions.

•Excess negative drift is indicated by 2.5 mA current output

•Sensor or controller/transmitter is connected or disconnected

•Long term or high concentration exposure to gas

- The RM2 is not designed to be repaired in the field. If a problem should
develop, first calibrate the device and carefully check for faulty wiring. If it is
determined that the problem is caused by an electronic failure, the device must
be returned to the factory for repair. Refer "How to Return Equipment" on
page 18 for detailed instructions.

- Apparent sensor failure (see "Calibration Failure/Interruption" on page 11)
may occur if calibration process has begun but span gas is not applied when
prompted or if span gas is removed during calibration process. Perform a
manual reset (refer to "Manual Reset" on page 11) and re-calibrate sensor.

- If Front Panel buttons appear non-responsive

—recycle power. (Can occur

when set up at Front Panel is interrupted by an attempt to also set up using
T erminal) . DOES NOT af fect detection functionalit y.

- Consult the manual supplied with the Fire Head, Millennium or Uni-Tran for
further troubleshooting information.

LECTROSTATIC SENSITIVE DEVICE (ESD)

Electrostatic discharge (ESD) is the transfer, between bodies, of an electrostatic
charge caused by direct contact or induced by an electrostatic field.

The most common cause of ESD is physical contact. Touching an object can
cause a discharge of electrostatic energy
occurs near electronic components, it can damage or destroy those components.

In some cases, damage is instantaneous and an immediate malfunction occurs.
However, symptoms are not always
or seemingly normal for an indefinite period of time, followed by a sudden
failure.

T o eliminate potential ESD damage, review the following guidelines:

• Handle boards by metal shields—taking care not to touch electronic

components

• Wear grounded wrist or foot straps, or ESD shoes or heel grounders to
dissipate unwanted static energy

• Prior to handling boards, dispel an y charge in your body or equi pment

• Ensure components are transported and stored in static safe packaging

• When returning boards, carefully package in the original carton and static
protective wrapping

• Ensure ALL personnel are educated and trained in ESD Control Procedures

In general, exercise accepted and proven precautions normally observed when
handling electrostatic sensitive devices.

A warning label is placed on the packaging, identifying product using
electrostatic sensitive semiconductor devices.

—ESD! If the charge is sufficient and

immediate—performance

may be marginal
