Function Description
Display 7 digits and minus display, Color amber
Display data Display data at power ON It is possible to set the display data for each axis at power ON.
Display switching The display data for each axis can be set by key operations.
Without comparator The calculation values for each axis can be selected and displayed in the
counter displays A, B and C. (Advanced settings and key operations)
1-axis input Factory setting : Display A : First axis current value,
Display B : First axis maximum value,
Display C : First axis minimum value
2-axis input Factory setting : Display A : First axis current value,
Display B : Second axis current value,
Display C : Off (Input axis switching is also possible)
With comparator Comparator : Display A : Data display for axis subject to comparator
display Display B : Comparator setting value display Upper
Display C : Comparator setting value display Lower
Measuring unit input resolution Standard : 0.1 µm, 0.5 µm, 1 µm, 5 µm, 10 µm, 1 s, 10 s, 1 min, 10 min
Expanded : 100 µm, 50 µm, 25 µm, 20 µm, 2 µm, 0.05 µm and 1 degree
can be added.
Display resolution Measuring unit input resolution or higher and supported inch units
Inch: Basic
: 0.000005", 0.00001", 0.00005", 0.0002", 0.0005"
Inch: Expanded : 0.000002", 0.0001", 0.001", 0.002", 0.005"
Input signal A/B quadrature signal, Z signal (Conforms to EIA-422)
Minimum input phase difference 100 ns
Calculation 1-axis input First axis current value, maximum value, minimum value, peak-to-peak
data value (Current value only when using high-speed BCD)
2-axis Without comparator Current value, maximum value, minimum value and peak-to-peak value of
input first axis, second axis and addition axis (Each axis can be calculated
individually.)
With comparator Current value, maximum value, minimum value and peak-to-peak value of
first axis or addition axis (1 + 2) (Calculation can be performed for only one
axis.)
Quantization error ±1 count
Alarm display Measuring unit disconnected, Excess speed, Maximum display amount
exceeded, Power failure, Error in stored data
Reset Key operation and external reset Current value reset, Alarm cancel
Restart START key and external input Restart of peak value calculation for each axis/all axes
Preset Preset/call by key operations, External recall It is possible to store/edit up to three values for each axis.
Master In combination with a measuring unit with a The master calibration value is relocated when going past the reference
calibration reference point point after the power is turned on.
function
Datum Datum point set/call by key operations It is possible to store/edit one value for each axis (when not using the
point master calibration function).
operations
Reference Reference point hold/relocation by key It is possible to store/edit one value for each axis (when not using the
point operations master calibration function).
