Number Name Function
⑩
Fine tuning LED This LED comes on while fine tuning is made.
⑪
Measuring range LED This LED indicates measuring range. The measuring
ranges of AS2503 and AS2603 are explained in 3-4
Measuring Range and 3-5 Measuring Range.
⑫
Calibration value setup knob
(CAL(με)) με=10
-6
First digit
Second digit
Third digit
Fourth digit
Indicated value is calculated value based on input. The
value can be set from 1με to 9999με by a step of 1με.
Pressing the knob changes the digit for calibration value
LED
⑬
and turning the knob changes values.
For further information, see page 2-6 How to Set
Calibration Value. The value the equivalent voltage value
based on a gauge factor of 2.0 and the one gauge
configuration (1mV/V=2000με).
⑬
Calibration value LED The LED displays calibration value and setting status
(digit blinking).
⑭
Calibration value application
switch
This switch is used to input the value that is set by
calibration value setting knob
⑫
. Pushing toward right
inputs a plus value (tension) and pushing toward left
inputs a minus value (compression). As a calibration
value is superimposed with the input signal to generate
the output voltage, return the position to OFF (middle)
after inputting the calibration value.
⑮
High-pass filter LED This LED comes on when the high-pass filter is used.
⑯
ON./OFF for high-pass filter
(FILTER)
Pressing the knob allows the high-pass filter to switch
between ON and OFF. High-pass filter LED
⑮
comes
on for ON and it comes off for OFF.
Filter type: 2-pole Bessel filter
Cut-off frequency: 0.5 Hz
Low pass filter setting knob
(FILTER)
This knob is used to set the low-pass filter. Turning the
knob allows the filter to be set to OFF (= W/B) or cut-off
frequency. The setting information is displayed on
low-pass filter LED
⑰
.
Filter type: 4-pole Bessel filter
Cut-off frequencies: 10, 30, 100, 1k, 30kHz, W/B
