6-1. Common calibration procedure
The three calibration methods available in the TD-260T,
equivalent input calibration, actual load calibration, and TEDS
calibration, follow the same steps before and after calibration.
Below is the flow chart of the calibration procedure.
Disable CAL lock (F3-5)
Set remote sense/TEDS (F2-6)
Set bridge voltage (F2-5)
Set minimum scale (F3-3)
Equivalent input calibration,
actual load calibration, or
TEDS calibration
Set display refresh rate (F3-4)
Enable CAL lock (F3-5)
Shown inside the brackets ( ) are setup screen numbers.
This section provides information about the steps to be
performed before and after calibration, followed by equivalent
input calibration, actual load calibration, and TEDS calibration.
6-1-1. Enabling and disabling CAL lock
Normally the TD-260T is used with the calibration lock set to
ON. Be sure to set the calibration lock to OFF before calibration,
and then set it to ON again after calibration.
1. Enter the setup screen number F3-5.
Press 3 times
Press 4 times
2. To select ON or OFF, press

To save, press:
CAUTION
<
The calibration lock setting changes the function of the
ZERO key.
If you press ZERO with the calibration lock set to ON, the
displayed reading is digitally set to zero.
With the calibration lock set to OFF, zero-point calibration is
performed.
<
To prevent the calibration values from being accidentally
changed, be sure to set the calibration lock to ON.
NOTE
For detailed information about setup items whose settings
cannot be changed with the calibration lock set to ON, see
the section 4-2. “List of setup items and settings.”
