This handheld display module provides an 8 digit LCD reading from up to 12 of the T24 Acquisition modules (strain gauge, voltage and current). The T24-HA can be operated in two modes:
- Result Mode sums the values from the ‘paired’ acquisition modules making this sum the primary displayed value.
- Item Mode allows the user to select which acquisition module value to display.
The acquisition modules can be ‘powered on’ and ‘powered off’ automatically by the handheld. Status indicators inform the user if the remote acquisition module has input integrity problems, low battery, low signal, over range or other error. The display can be toggled between gross and a tared value and can optionally be scaled to change measurement units.
In addition, a function key can be configured to retransmit the displayed value to other T24 modules such as a printer.
The licence free 2.4GHz direct sequence spread spectrum (DSSS) radio technology offers high integrity, error free communications which can co-exist with other wireless technologies such as Wi-Fi, Bluetooth® and Zigbee®. FCC, ETSI and IC approvals.
This handheld module uses a pair of standard alkaline AA batteries and is configured using free T24 Toolkit software which runs on a PC connected to a T24 base station.
The handheld display is typically seen in applications requiring wireless loadcell measurement or wireless strain gauge display. To learn more about these applications please see our 'Industries' tab.
