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, the
unit is switched to warm-up status turning all outputs OFF.

Input display: Indicates the input value.
Indication of -2000 or less: The minus (-) sign and
input 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 the
Input display for 3 seconds after power
is turned ON.
Set value display: Alarm 1 (A1) to Alarm 6 (A6) values are
indicated (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.
(A1
A2 • • • • A6
A1).
When power is turned ON, A1 value is indicated.
When alarm output is ON, “
” and the value selected
in [Display selection] are alternately indicated on the Set
value display. If the UP Key is pressed together with the
DOWN 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 is
turned ON.
