Page 4: Introduction / Overview
The PSD (Portable Sensor Display) product group is a range of hand-held instrumentation which will cover different sensor types in the future. The PSDS-HSBK (Portable Sensor Display Standard) for strain bridge sensors is a microprocessor based portable display instrument designed to interface with any full bridge sensor with an output sensitivity of up to 480mV/V.
Page 5: Advanced Flexible Multi-Point Calibration
These display modes are independent to whatever Calibration Range is currently selected. Decimal Point Position and Resolution Because the PSDS can handle so many engineering units out of the box and allow conversion between suitable units the way it handles decimal point positions and resolution (For displays) needed a complete overhaul compared to the original PSD.
Page 6: Teds (Transducer Electronic Data Sheet)
Out of the box the decimal point position for all units has a sensible default but these can easily be changed using the keypad (until the user chooses to disable that feature) by long presses on the left and right keys. When you are viewing a particular unit simply adjust with the keys and this setting will be remembered any time that unit is selected in any calibration range or a TEDs device is connected showing that unit.
Page 7: Advantages
conditioner interrogates the sensor, it can interpret the self-identification data. This technology provides a great benefit by eliminating the need for paper calibration sheets. And because all sensors produced according to the standard will carry the same basic identically formatted self-identification information, you will be able to mix and match sensors and applicable signal conditioners across manufacturers.

calibration). This could be used to provide multiple calibrations for the transducer, for example high range, low range, tension & compression. Typically, a TEDS-enabled transducer would be supplied with one additional calibration template. The default behaviour is to select the first calibration template, or the standard 2-point if a calibration template is not found. The user can cycle between all the available calibrations unless this feature has been restricted.
Page 9: Configuration Customization
A forgotten password cannot be recovered but the protected sections can be unprotected again, but this will involve contacting your supplier as Morehouse will need to verify that you have the rights to the protected data. There will be a charge for this service.
Page 10: Measurement Block
Measurement Block The following diagram shows how values and flags are generated. This entire block is processed at the Measurement Rate selected. Some processes (such as the calibration and linearization) are only shown as a single block due to their complexity. Key: Rev: 2 Page 10 2/2024...
Page 11: User Operation
User Operation Keypad The keypad has some functionality that is fixed and some that can be configured and some that changes depending on what is on the LCD display. The handheld can optionally sound a beep when keys are pressed. Function The top right key doubles as the power key.
Page 12 When not in a menu the Up/Down keys can perform one of a few user definable functions but the default is to cycle through all available calibration ranges. If a TEDS device is attached then these keys will cycle through any valid Calibration Tables held in the device.
Page 13: Display
Display The PSD has a monochrome dot matrix backlit display and the display may change depending on the display mode. However, the basic operation and positions of items should remain intuitive. The example shown below allows up to three values to be displayed where one is a large, primary value with two secondary values.
Page 14: Cumulative Zeroing
Soft keys allow you to select from alternative units and to switch between Gross and a zeroed Net value. The state of Gross or Net is displayed above the main value to the left. Cumulative Zeroing Similar to simple mode but has the advantage of being continuously able to zero the main display whilst still viewing the Gross value.
Page 15: Delta
Soft keys allow you to toggle between Zeroed and Gross values and to Reset the min and max to the current value. The usual Units selection is also available. Delta Similar to Min / Max above but this allows you to focus on the change in value, or noise. The display shows the Delta (Difference between Min and Max values) as the main value while the min and max are displayed underneath.
Page 16: Icons
Icons The set of icons displayed along the top left of the display are common to all display modes and have the following meanings. A warning is detected. Further investigation of External USB power has been applied. the warning may be required either via the keypad or software.
Page 17 Message Reason INPUT HIGH The mV/V input exceeds the upper limit for the selected sensitivity range of the current calibration range. INPUT LOW The mV/V input is below the lower limit for the selected sensitivity range of the current calibration range. OVERLOAD The input value exceeds the user level set as overload.
Page 18: Menu
Menu Menu Basics The menu is accessed by holding the OK key for around one second. It is possible to lock out the menu system so if your handheld does not display a menu it may be that your supplier has locked this feature. Individual features may also have been hidden by your supplier.

Page 26: Editing Parameter Values
Editing Parameter Values Some menu items allow you to edit / enter a numeric value or text. Editing Numeric Values The following example screen shows what would be displayed for editing the Alarm Low level. The text at the top right states the engineering units of the value being entered. The text at the top inside the box states what parameter is currently being edited.
Page 27: Editing Text
Pressing and holding this key for over a second then releasing will cancel the current edit. Editing Text The following example screen shows what would be displayed for editing the name of a calibration range. The text at the top inside the box states what parameter is currently being edited. One of the characters will be the current selection and this character will flash alternatively displaying its character and an underlined space.

Pressing and holding this key for over a second then releasing will cancel the current edit. Connections Strain Bridge Sensor Field Cable Connector Wiring To attach this connector to the handheld, align the white arrow on the connector with the white line on the handheld socket then rotate the locking collar as indicated on the connector.
Page 29: Field Cable Preparation (4 Wire Shown)
Blue TEDS Black Ground Shield/Screen Grey Cable screen should only be connected to chassis of the sensor. If this cannot be achieved then it should be connected to Excitation –ve. View from solder connector side of the connector Field Cable Preparation (4 Wire Shown) Strip 15 to 20mm of outer sheath.
Page 30: Connector Assembly
Connector Assembly If a cable is already connected to the connector remember to unscrew the cable clamp before unscrewing the main body of the connector otherwise, you risk twisting the cable and breaking the connections. If the main body is difficult to unscrew it may be easier to lock the connector to the handheld then grip and unscrew the main body in an anti-clockwise direction.
Page 31: Wiring A Six Wire Strain Bridge Sensor
Wiring a Six Wire Strain Bridge Sensor Where possible six core cable should be used to connect the strain bridge sensor directly to the PSD connector. If the cable has twisted pairs refer to the wiring table above where it is indicated which connections should share a twisted pair.
Page 32: Where Strain Bridge Sensor Chassis Is Metallic (Or Surrounding Strain Bridge Sensor Structure)
Where Strain Bridge Sensor Chassis is Metallic (or surrounding strain bridge sensor structure) Cable shield should be connected to the strain bridge sensor chassis and remain unconnected at the PSD end. Where There is No Option to Connect to Strain Bridge Sensor Chassis Cable shield should be connected to the PSD Excitation -ve and remain unconnected at the strain bridge sensor end.
Page 33: Toolkit Configuration
Toolkit Configuration The toolkit (Windows 10 & 11) is used to configure the handheld and offer many more configuration options than the in-built menu system of the handheld itself. Everything that the user can interact with in the Toolkit is highlighted in the blue accent colour. Home When you connect the handheld to the PC using a USB cable it creates a virtual COM port on the PC.
