(2) HOLD Mode: {HOLD}
In this mode whether the analog output is held or not in measurement mode, can be selected. This
function is available when the hold function is set to “1: Enabled” in SET HOLD mode at the setting
level. If the function is set to “0: Disabled,” this mode will be skipped.

If the hold function has been set to “1: Enabled” in SET HOLD mode at the setting level, the instrument
automatically goes into this HOLD mode when it returns from any level to measurement mode, with
the exception of DISPLAY mode.
(3) RANGE Mode: {*RANGE}
In this mode, an output range corresponding to analog output 1 and 2 can be set. Enter turbidity
values corresponding to a 4 mA (or 0 mA) output signal (zero point) and a 20 mA output signal (span
point).

*6: Zero and span points should be set together. Only after span point has been entered, both
zero and span points are accepted. Cancellation by pressing [MODE] key during the
procedure will not change either of the points.
