Loadstar Sensors
Quick Start Calibration for DI-1000, DI-1000Z and DI-1000ZP
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-1000 unit to make sure the
connections are tight.
3. The DI-1000U is powered by the USB and does not need external power. If you
have a DI-1000Z or DI-1000ZP, then connect the power supply first.
4. Then connect one of the following:
o If the unit is not wireless enabled, connect the USB cable between the computer’s
USB port and DI-1000 unit.
o If your DI-1000 is wireless enabled (Z or ZP models), first connect the power supply
to the DI-1000Z or ZP unit. Then connect the XBee USB Adapter to the computer’s
USB port.
You could also use the wired connection to calibrate and then switch to wireless
connection during operation.
Step 4 will add a USB Serial Port entry to the Device Manager.
5. Use Hyperterminal program to establish communications with the DI-1000. 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’.
6. 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).
