Attached Functions
Auto-light function: Automatically measures and controls
brightness of the displays to conserve power.
Power failure countermeasure:The data is backed up in non-volatile IC memory.
Self diagnosis: The CPU is monitored by a watchdog timer,
and when an abnormal status is found on the CPU, theunit is switched to warm-up status turning all outputs OFF.

Environmental Specification
RoHS directive compliance

Indication of -2000 or less: The minus (-) sign andinput value light alternately.
Indication of 10000 or more: The lower 4 digits flash.
Under range: -10% of input span or less:“” flashes on the Input display.
Over range: 110% of input span or more:“” flashes on the Input display.
Warm-up indication: The input type is indicated on theInput display for 3 seconds after poweris turned ON.
Set value display: Alarm 1 (A1) to Alarm 6 (A6) values areindicated (follows the selection in “Display selection”.).
If the UP Key is pressed for 1 second during alarm value
indication, alarm values will be switched thus.
(A1A2 • • • • A6A1).
When power is turned ON, A1 value is indicated.
When alarm output is ON, “” and the value selectedin [Display selection] are alternately indicated on the Set
value display. If the UP Key is pressed together with theDOWN Key in the above status, the alarm output
currently being turned ON will be displayed.
(E.g.) If Alarm 1 and Alarm 3 outputs are ON, “”
and “” are displayed in order.
Power indicator: The green LED is lit when power isturned ON.
