ONE-STEP-CAL CALIBRATION
CONFIGURATION MODES & DIP SW
When you program the transmitter module, two configuration modes are available: Field Configuration using DIP SW
/ control buttons, and PC Software. (Option B type is for the
field configuration only.)
The internal DIP switches are used to configure input and
output type. Once the module is configured, precise ranges
are set up with the front control buttons using a simulator
connected to the input terminals and a multimeter connected
to the output terminals as a reference.
INPUT & OUTPUT RANGING
For example, suppose that the DIP switches are configured
for the voltage pulse (0 – 100kHz full-range). Turn the power
supply to the transmitter on and press MODE button to enter to the Input Calibration Mode. Apply the desired minimum (e.g. 0 Hz) and maximum (e.g. 1 kHz) input levels and
push the DOWN (zero) and UP (span) respectively to set the
input range to 0 – 1 kHz.
FINE ZERO & SPAN ADJUSTMENTS
After the transmitter is installed and operational, fine zero
and span tuning can be also performed using the front control buttons. Both zero and span are adjustable within ±15%.
PC SOFTWARE CONFIGURATION
When you need to apply the same setting to multiple transmitters, downloading one setting from the PC is convenient.
The PC Configurator Software (model: M3CON) is available
separately.
Turn the transmitter to PC Configuration Mode (See Table
1) and all programmable features can be set up on a PC regardless of other DIP SW setting except for the following:
the output type must be selected with the DIP SW1-1 through
SW1-4 (See Table 11), and the pulse sensing type and noise
filter must be selected with the DIP SW4-1 through SW4-3
(See Tables 8 and 9).
For detailed information on the PC configuration, refer to
the M3CON instruction manual.
Then the output range can be calibrated in a similar manner after moving to the Output Calibration Mode by pressing MODE button again. Increase or decrease the simulated
input until the output meter shows the desired levels and
push the DOWN (zero) and UP (span) respectively for the
minimum (e.g. 4mA) and maximum (e.g. 20mA) levels.
The front LEDs’ colors and flashing patterns help you to easily
identify the transmitter’s status and confirm the setup actions in each step of Calibration Modes. See detailed explanation in “Calibration Flow Chart.”
The calibrated input and output ranges are stored in the
internal memory. The module reads the DIP-switch-calibrated configuration only once after the power supply is
turned on. Set the switches with the power supply removed.
