Minimizing tact time
with sequence control
High-speed comparator and external input/output
■ EXT.I/O
Loading of saved settings from panel……LOAD 0 to 4
Measurement start trigger input…………TRIG
Measurement end signal output…………EOC
Comparator output…………………………Hi, IN, Lo
Internal power supply +5 V (max. 50 mA)……INT. DC V
Internal GND………………………….………INT. GND
● Comparator with external output
You can set the upper and lower limits, and display one of 3
results: Hi, IN or Lo. In addition to LED and buzzer results,
open collector output results are provided through the external
input/output terminals.
X: measurement value, H: Upper limit, L: Lower limit
X > H…………………………Hi
H ^> X ^> L…………………IN
L > X………………Lo
With external control
■ Save/Load function for rapid response to various
work situations
You can save and recall a maximum of 30 DMM setting
conditions for various range and comparator values.

■ A trigger delay designed for measurement safety
The 3237, 3238 and 3239 are equipped with a trigger delay
function that can be set to manual or automatic for the time
period between trigger input and the display of the comparator
result (see T2 in the figure above).
Manual settings: Designate periods in terms of millisecond intervals between 0.000 s and 9.999 s
