HANDY CAL
calibrator
|
|
|
The
CA51/CA71 HANDY CAL calibrators are comprehensive generating/measuring
instruments
|
|
|
for all your calibration
and equipment checking needs at maintenance sites. The CA51/CA71
|
|
|
can
simultaneously generate and measure voltage, current, TC, RTD and pulse
signals, thus you
|
|
|
dont need to prepare many
instruments. In addition, the incorporated rotary switches of good
|
|
|
repute
enable operations so smooth that an incorrect measurement caused from
erroneous
|
|
|
operations can be prevented.
