SET TRANSFER Mode
(relay on or off)
From the moment output hold is initiated (during cali-
bration, from TEST/MAINT menu or by TTL input), the
elapsed time INTERVAL or DURATION countdown for
a TIMER relay is temporarily suspended. Also, any
TIMER relay counting down DURATION time is turned
off. When output hold is released, a TIMER relay re-
sumes its INTERVAL or DURATION countdown from
the suspended time. When a TIMER relay is counting
down DURATION time, both outputs are temporarily
held until after the preset DURATION time (and OFF
TIME, if used) elapses.

Normally, each CONTROL and ALARM relay is active, re-
sponding to the measured value of its assigned parameter
(pH or ORP, or temperature). During calibration, however,
you can transfer (XFER) each relay to a preset on/off
transfer state to suit your application requirements:
