HTs-7LS

Overview

The Hobart HTs-7LS is a service scale for weighing and price computing in food retail settings. It has a listed capacity of 30 lb, an embedded Linux operating system and a 10.1-inch colour operator touchscreen. The scale can print product labels, with operation based on product records such as PLU numbers, pricing and tare. The HT Series operator manual covers the HTs-7LS alongside other HT Series models; features described as part of the series may depend on system setup.

For store operations, the HT Series system can store information on thousands of products, subject to available system space and memory. Product records can include PLU and UPC numbers, price, tare and shelf life. The system can also hold consumer-facing content such as Nutrition Facts, safe-handling information, expanded text, health tips, meal planners, recipes, cooking instructions and merchandising graphics.

Key Features

• Price-computing service scale: Weigh products and use product information, including price and tare, in scale transactions.
• Touchscreen operation: The 10.1-inch colour operator touchscreen provides access to scale features and screens.
• Label printing: The HT Series manual describes printing product labels from PLU records and identifies printer alerts for issues such as an open label cassette or an empty label supply.
• Multiple operating workflows: The manual describes manual mode for individual transactions and prepack mode for repeated labelling of products with the same PLU.
• Product information: PLU records can hold product-handling, pricing and consumer information. Available fields and label content depend on how the system is configured.
• Communications: The HTs models have one USB port. The HT Series manual also identifies an RJ-45 Ethernet connection and an audio jack.

Installation & Requirements

The manual specifies 120 V, 60 Hz, single-phase electrical service (two-wire plus ground). A power cord is provided and connects to the bottom of the scale. The parts listing for the HTs Series identifies a 120 V power cord. The manual states that installation and moving should be performed only by a qualified Hobart Service Technician.

The HT Series system is specified to operate within 14°F to 104°F (-10°C to 40°C). An RJ-45 jack is available for an Ethernet TCP/IP connection. The HTs models have one USB port, rather than the two USB ports identified for other HT Series models. An audio jack can connect external headphones; when it is in use, the scale speakers are muted. The provided information does not specify clearance or ventilation requirements.

Operation

Operator screen and navigation

The operator screens are touchscreens for entering information and accessing scale features. The manual describes three screen locations and navigation by touching the screen-view controls or swiping between screens. Common screen elements include the Home and Menu icons, a Rezero icon, capacity information, a zero indicator, alerts, the scale operating mode, operator name when login is required, and date and time. HTs models do not use the left screen unless equipped with the browser function.

The Rezero icon is used to zero the weigher when nothing is on the platter. The capacity area shows the scale capacity and current capacity range. A zero indicator appears when there is no weight on the scale and it has been zeroed. Alerts can notify the operator of user messages, printer issues, planogram messages or network connectivity changes. A red, flashing printer alert can indicate an issue such as an open label cassette or no labels. A lost network connection can be shown by a flashing red connectivity icon; network details are available if enabled.

Scale modes and label workflows

In manual mode, which the manual identifies as typical for deli-counter transactions, the operator places a product on the scale, enters its PLU and touches the print icon to print a label. In prepack mode, described for repeated transactions such as meat-room work, the operator places the product on the scale and enters its PLU. When the weight is stable, the label prints without touching the print icon. The product information remains on screen after a label prints, allowing another package with the same PLU to be weighed and labelled.

The manual also describes item-entry options. Normal entry is one option; Accumulate Items and Production Entry are available in manual mode. Accumulate Items is intended for operations such as bakeries where multiple PLUs may be part of a transaction. Depending on configuration, it can print a label for each product, an item-total label, or itemized receipts. Production Entry can be used to enter several fixed-weight or by-count PLUs and the number of labels required for each, allowing multiple label runs to be prepared in one operation. The manual notes that streaming labels may be useful with Production Entry; this prints labels without removing their backing paper.

Product records and system content

Supervisors can set up product records in the scale database. The manual refers to products as PLUs and describes fields for product details, pricing, label information, tare and shelf life. Other available product content includes Nutrition Facts, safe-handling text, expanded text, health tips, meal planners, recipes, cooking instructions and merchandising graphics. The system can also use UPC information. What appears on an operator screen or printed label depends on the configured fields, label type and system setup. The manual notes that a suitable Nutrition Facts label type must be assigned for Nutrition Facts content to be available.

Cleaning & Maintenance

The HT Series cleaning instructions specify that the printhead should be cleaned with a cotton swab and alcohol every time a label roll is changed. The instructions also call for cleaning the roller on the label cassette with a cotton swab and alcohol. Remove the label cassette from the scale to access it for cleaning.

Wipe the platter, display and housing daily with a clean cloth and mild detergent solution. Do not dampen labels, electronic parts or connections, and do not allow water to enter openings in the housing, as this could damage the scale system. Do not use a metal tool on the printhead; it could scratch or break it.

Troubleshooting

The operator screen includes separate alerts for user messages, printer issues, planogram messages and network connectivity. Touch an alert icon to view its message. A printer alert can indicate that the label cassette is open or that the scale is out of labels. Check the displayed message to identify which printer condition is reported. A network icon may show a wired connection or wireless signal strength; if connectivity is lost, the icon flashes red, and network details can be viewed if enabled. The manual also describes a user alert that flashes red when a message is available.

Applications

The HTs-7LS suits service-counter weighing and price computing where staff select products by PLU and print labels. The manual describes manual mode for individual transactions, such as those at a deli counter, and prepack mode for repeated package labelling, such as in a meat room. Accumulate Items supports workflows such as bakery transactions involving more than one PLU, while Production Entry supports planned runs of labels for multiple products. These workflows rely on product records and system configuration appropriate to the operation.
