In most cases, products with the minimum current output are clear and readings will be consistent with factory

calibration. Only recalibrate the low end of the range in situations when all products are producing an output greater

than 40%.

Should the low end of the range require adjustment, please contact the KAM factory directly at +1 713 784 0000.

Though the KAM

OID™ sensor is factory calibrated it should be calibrated in the field to suit specific application

requirements and fuels. Increasing or decreasing the sensitivity will allow the instrument to maintain the highest

resolution possible while detecting the interface of all possible fuels.

INCREASE SENSITIVITY WHEN all readings are typically falling in the lower or

middle portion of the KAM

OID™ output range. Increasing sensitivity elevates the output

range to provide greater interface resolution.

DECREASE SENSITIVITY WHEN some products exceed the maximum reading of

the pre-calibrated settings. Products that exceed the pre-set calibration readings will

produce an off-scale reading exceeding 20mA. Decreasing sensitivity lowers the output

range of the KAM

OID™ sensor to allow all readings to fall within the 4-20 mA output ranges.

CAUTION: When multiple KAM

OID™ sensors are being used on the same system, each sensor should be

calibrated equally. If unique calibration is applied to one unit, its output will vary from those of other units

measuring or monitoring like products.

The calibration procedure consists of increasing the gain or reducing the gain as needed to increase

or reduce sensitivity.

LED light output settings are pre-set at the factory and should not be adjusted.

REQUIRED TOOLS: VOLT METER, SMALL FLAT-HEAD SCREWDRIVER

CHANGING THE HIGH END OF OUTPUT RANGE

CHANGING THE LOW END OF OUTPUT RANGE

Determine which product produces the highest current output.

Connect a volt meter across 4-20 mA terminals. When the highest output product is flowing, increase the

gain by turning GAIN counterclockwise or decrease by turning clockwise. As you are turning, look at your volt

meter and stop when it reads 16.8 mA or 80% of scale. See FIG. 4-1 on page 18.

FOR ALL OTHER TYPES OF ADJUSTMENTS CALL KAM CONTROLS, INC. +1 713 784 0000.
