Attached Functions
Light sensor: Automatically measures and controls brightnessof the displays, saving energy.
Power failure countermeasure:The data is backed up in non-volatile IC memory.
Self diagnosis: The CPU is monitored by a watchdog timer, andwhen an abnormal status is found on the CPU, the unit isswitched to warm-up status turning all outputs OFF.

Environmental Specification
RoHS directive compliance

Settings
Function Keys
(1) UP Key: Increases numeric value.
(2) DOWN Key: Decreases numeric value.
(3) MODE Key: Selects a setting mode.
(4) SUB-MODE Key: Lights the displays again when in unlit
status.

Displays and Indicators
Input display: Indicates the input value.
When a range with a decimal point is selected:
Indication of -200.0 or less: The minus (-) sign and input
value light alternately.
Under range: “” flashes on the Input display.
Over range: “” flashes on the Input display.
Warm-up indication:For approx. 3 seconds after the power to the instrument isturned on, input type is indicated on the Input display, andOutput 1 type is indicated on the Output display.
Output display: Indicates the output volume in percentage (%)
form.
Power indicator: A green LED is lit when the power to theinstrument is turned on.
