ZERO
Calibration
The digital zero function zeros the indication given at an arbitrary timing.
Thereafter, the function shows the amount of change from the point of
zeroing. However, this function serves as an indication resetting function for
a frequency measuring unit. Thus, the digital zero function can be used to
reset the indication when there is no input signal at all.
Note that, the on/off control of the digital zero function can be achieved by
means of terminal control or front panel keys. In the case of terminal control,
the digital zero function is turned on by short circuiting the ZERO and COM1
terminals or setting both terminals to the same voltage level. The indication
at that moment is zeroed. In the case of control with the front panel keys,
hold down the enter key and press the increment for about 1 second to zero
the indication at that moment.
1. Method of Setting zero
Pressing the
key while pressing the
key
and zero set mode.
※ Note : The setup condition are protect clear.
If these conditions are not satisfied, an error indication appears
and the display returns.

ON/OFF setting can be performed by pressing by pressing the “increment”
key one at a time.
When backup is set to OFF, Digital ZERO continues even when power is
turned OFF/ON.
