Auto-light function: Display brightness is controlled in accordancewith the surrounding area. Unnecessary brightness is reduced,+ 1
saving energy.
Power failure countermeasure: The data is backed up in non2
volatile IC memory.
Self diagnosis: The CPU is monitored by a watchdog timer, and Power supply for 3
when an abnormal status is found on the CPU, the unit is 2-wire transmitter
switched to warm-up status with tuning all outputs off.

Indication of -2000 or less (for DC input):
The minus (-) sign and input value light alternately.
Indication of 10000 or more:
The lower 4 digits flash.
Under range: “” flashes on the Input display.
Over range: “” flashes on the Input display.
Warm-up indication: For approx. 3sec. after the power to theinstrument is turned on, the input type isindicated on the input display, and Output
type is indicated on the Output display.
Output display: Indicates output volume in percentage (%) form.
Power indicator: The green LED lights when the power to the
instrument is turned on.
