9. Digital Zero Function
9-1. Digital Zero
You can set the currently displayed reading to zero.
1. Press ZERO or short-circuit the control input/output
terminals A8 for D/Z and A9 for COM.
<
To set a range that can be digitally zeroed, use Digital Zero
Limit (F1-13).
<
To clear the digitally set zero, shut off the power to the TD-
260T or perform Clear Digital Zero (F1-14).
CAUTION
<
The Digital zero function is available only with both CAL
Lock (F3-5) and Enable Digital Zero (F3-5) set to ON.
<
If you press ZERO with the CAL Lock (F3-5) set to OFF, zero-
point calibration is performed instead.
9-2. Digital Zero Limit
You can set a range that can be digitally zeroed. (Note that a
value that is set for Digital Zero Limit does not use mV/V as the
unit of measure.)
1. Enter the setup screen number F1-13.
Press once
Press 3 times
2. To change the blinking digit of the value, press
5
or
b
.
To move to the previous or next digit, press
g
or
t
.
To change the digit, press:
To move to the previous
or next digit, press:
3. To save the value you set, press ENTER, and then to
exit the setup mode, press ESC.
To save, press:
CAUTION
If the current sensor input exceeds the digital zero limit
setting, the TD-260T, which regards as zero the sensor input
that was obtained when the zero-point calibration was
performed, shows Err14, meaning digital zero limit error, and
cannot set the displayed reading to zero.
NOTE
If you perform the function explained in the section 9-3.
“Clear Digital Zero,” the TD-260T displays the current sensor
input value, regarding as zero the sensor input that was
observed when the zero-point calibration was performed.
