Trigger functions for monitoring of all four channels
In all of the functions, including the memory recorder and
recorder, all eight analog input channels and sixteen logic input
channels can be used for trigger input. In addition to a level
trigger, which compares voltages based on a reference value,
the 8835-01 supports the following triggers.
● Window trigger that compares voltages based on two reference values
● Voltage-drop detection trigger that detects voltage drops in commercial
power lines
● RMS-value level trigger that compares signals based on the RMS-value level
● Period detection trigger that measures periods and detects all deviating
periods
● Pattern trigger that compares signals based on the logic signal ON/OFF
pattern
Variable (span adjustment), vernier (fine adjustment)
When sensors are used to measure and record noise,
temperature, acceleration or other physical quantities, precise
calibration is important. This is facilitated by the vernier
function that allows fine adjustment of amplitude. The variable
function lets the user numerically specify the measurement
span, such as 1 - 5V or 4 - 20mA. This is useful for matching
the range of instrumentation to the full span of the recording
paper. A scaling function for converting measurement results is
also available.
Manipulation using the cursor
Use of the two cursors on the screen enables the user to read
the time difference and potential difference.
DC input
(The DC POWER ADAPTER 9439
must be used)
External trigger input
Trigger signal output
Signal outputs, control inputs, DC input
The results of waveform decisions, parameter decisions, and
triggers are output as open collector signals. The
-01 is
8835
also provided with signal inputs for remote control of the start,
stop, and print buttons.
The
-01 has a dual AC/DC power-supply specification,
8835
DC
and an external battery can be used by means of the
POWER ADAPTER
, in addition to normal AC power
9439
supply. This allows vehicle-mounted applications, where
an AC power supply is not available. If both supplies are
connected, the AC power supply takes precedence, but if
the AC power fails, the unit automatically switches to DC
operation.
External control

Judgment outputs
*When using the F/V UNIT 8940 with 12 V DC power, the printer can only be
used for up to 2 channels.
