Communication With External Devices (continued)
Digimatic
Digimatic output is used for Mitutoyo data collectors and printers (refer to RS232 memory data output instructions).
Analog
Analog output is very linear and can have a high response time (1mS). This voltage is directly related to the unit of measurement.
Specifications:
Voltage: -1VDC~0~+1VDC
Load Impedance: 2K or higher
Response Time:
1mS - with analog output mode “on”
display update time - with analog output mode “oFF”
To change analog output mode:
1. Press the PEAK button while holding down the ON button; “dSP” will appear on the small display.
2. Press the PEAK button seven times. The small display will indicate “dAf” and the main display will reflect the
current setting.
3. Each time the > button is pressed, the main display will toggle between “on” and “oFF”.
4. Press the MEMO SET button to store analog output mode and exit.
Comparator
Once high and low limits have been set (refer to “Setting High and Low Limits” section), the comparator output may be
used to turn on a light or sound an alarm for “go - no go” testing.
HI (yellow)
GO (green)
LO (red)
GND (black or blue)
TRIGGER INPUT (white or brown)
Comparator cable
HI point is defined as: HI
OK or GO is defined as: LO < Data < HI
LO point is defined as: LO>Data
NOTE: The comparator cable is also used for external control input (see following section).
