Need help?Do you have a question about the Cardinal Detecto 6732 and is the answer not in the manual?
The Detecto Model 6700 Series Neonatal Scale is a solid-state digital instrument designed and manufactured in the USA for accurately weighing newborn infants. This scale is built with reliable electronic circuitry to ensure precise measurements, even when an infant is moving.
The primary function of the Neonatal Scale is to measure the weight of newborn infants. It provides an easy-to-read LED display for weight readings. The scale is equipped with a lb/kg key, which allows for quick conversion between pounds/ounces and kilograms/grams, catering to different measurement preferences. When the lb/kg key is pressed after the scale has locked a weight on the display, it converts the displayed weight from lb/oz to kg/g, or vice versa. Appropriate indicators illuminate to show the current unit of measurement.
A key feature for practical use is the TARE/ZERO function. This allows users to subtract the weight of a blanket or cover placed on the scale platform, ensuring that only the infant's net weight is displayed. When the scale is unloaded, pressing the TARE/ZERO key resets the scale to zero.
The scale also incorporates a CLEAR WT. key. This is particularly useful during weighing operations where infant movement might cause the display to continuously flash. Pressing the CLEAR WT. key in such instances locks the weight on the display, providing a stable reading. The locked weight remains on the display even after the infant is removed from the tray, until the CLEAR WT. key is pressed again to clear it.
In addition to weight measurement, the scale tray itself includes a built-in length measurement scale, marked in inches, for conveniently measuring the infant's length.
To begin using the scale, first ensure it is placed on a stable, vibration-free surface, away from direct sunlight or rapidly moving air sources. The scale should be leveled by adjusting its four legs until the bubble in the level gauge (located on the weigh bridge) is centered. Once leveled, the legs should be locked in place by tightening the lock nuts. The infant tray is then placed on the scale, aligning the screw holes and securing it with the provided nylon screws, ensuring not to overtighten them and that the tray does not touch any surrounding objects.
The scale is powered on using the switch located on the right end of its backside. Upon activation, the scale performs a brief test routine, displaying information on all segments before showing zero, indicating it is ready for use.
The typical weighing procedure involves placing a blanket or cover on the scale tray, then pressing the TARE/ZERO key to zero out its weight. This ensures that the NET indicator illuminates, and the display shows zero. The infant is then placed on the scale. The display will initially flash, indicating a changing weight, then slow down, and finally stop, locking the weight on the display. If the infant's movement causes the display to flash continuously, the CLEAR WT. key can be pressed to lock the weight. After the weight is read, the infant and blanket are removed. The CLEAR WT. key is pressed to clear the locked weight, and then the TARE/ZERO key is pressed to prepare the scale for its next use.
Proper care and maintenance are crucial for the longevity and accurate operation of the Neonatal Scale. Users are advised not to subject the infant tray to sudden shocks, as this could damage the instrument. When operating the keyboard, only a light touch with a finger is necessary; sharp objects should not be used to press the keys.
Cleaning the scale requires caution. It should never be submerged in water or sprayed directly with water. Instead, the cover and infant tray should be cleaned with a damp cloth and a mild detergent. Abrasive cleaners, acetone, or other volatile solvents should not be used, as they can damage the scale's surfaces. The infant tray is also not designed for autoclaving.
In the event of a fuse replacement, it is imperative to use the correct type: a BUSS 3AG 1/4 ASB type for 115 VAC models, or a BUSS 3AG 1/8 ASB type for 230 VAC models. Before attempting any fuse replacement, the power cord must always be unplugged from the wall receptacle. The fuse is conveniently located on the right rear underside of the scale.
The manual also outlines error and fail messages that may appear on the display, such as FAIL A (bad electrical component), UnStb (unstable platform), LOD (no infant tray on scale at startup), UnLOD (weight on tray at startup), -OL- (capacity exceeded), and -Lo- (gross weight less than 0). These messages provide immediate feedback on potential issues. Users are strongly advised not to attempt repairs themselves and to contact their Detecto dealer if problems persist after checking basic troubleshooting steps like power cord connection, power switch status, AC power supply, circuit breaker, and adherence to operation procedures.
