Loadstar Sensors
Quick Start Calibration for DI-100
1. If you have purchased LoadVUE, install LoadVUE. This will also install the drivers needed.
If you do not have LoadVUE, use the Drivers CD to install the drivers.
2. Check the cable connections from the load cell to the DI-100 unit to make sure the
connections are tight.
o Connect the USB cable between the computer’s USB port and DI-100 unit. This will
add a USB Serial Port entry to the Device Manager.
3. Use Hyperterminal program to establish communications with the DI-100. See the
document “Driver Installation and Hyperterminal Operation of iLoad Digital USB Sensors
and Interface Devices”. (The default baud rate is 9600. ) Press <Enter> in Hyperterminal
and you should get a response ‘A’.
4. To calibrate using mVolt/V type the following commands in sequence in Hyperterminal.
Commands are not case sensitive. For example, to calibrate a 250 lb load cell with a 3.02
mVolt/V rating:
UNITS LB
LC 250
CAL m
MVOLT 3.02 (This number will be available from the load cell
calibration/specification certificate.)
TARE (this zeros out the load)
WC (this will continuously output the load in lb. Change the load and ensure
that the output changes).
5. To calibrate using a known weight type the following commands in sequence. Commands
are not case sensitive. For example, to calibrate a 250 lb load cell using a known load of 100
lb, remove all load from load cell and type:
UNITS LB
LC 250
CAL 2
2PCAL 100
<Apply Point 1 Load of 0 LB Press C when ready or Q to quit> C
<Apply Point 2 Load of 100 LB Press C when ready or Q to quit> Apply 100 lb, then type C
TARE
