Option Description
Setup base Select the sampler base (All weather refrigerated, refrigerated, portable standard or
portable compact).
Language Select the language of the controller.
Liq sensor cal Calibrate the liquid sensor or set to default.
Set contrast Adjust the contrast of the LCD screen.
Pump duty cycle Change the pump duty cycle. Range: 50% to 100% (default: 100%).
Password setup Set up a password to control access to the program setup and the system setup menus.
Select ENABLE>YES to set a new password or ENABLE>NO to activate the current
password. If the password is set for the first time, use 900900 as the current password.
Tubing life Set a reminder when the pump tubing is to be changed. Go to ENABLE>RESET
CYCLES to reset the pump cycle count to 0. Go to ENABLE>CYCLE LIMIT to change
the number of pump cycles that is used for the reminder. Go to ENABLE>STATUS to
show the current number of pump cycle counts.
SDI–12 (optional) Configure the operation of an SDI–12 device. This option is shown only when a device is
found.
Configure the SDI-12 device
A sensor such as a sonde can connect to the optional SDI-12 interface. The controller can get up to
nine measurements from one SDI-12 sensor. The sensor data can then be used as a trigger in
setpoint sampling applications. Configure the parameter type and unit, and set how often the
SDI-12 device is scanned for new measurement data.
1. Select Menu>System Setup>SDI-12.
Note: The SDI-12 option is only shown when an SDI-12 device is found by the controller.
2. Select one of the options:
Option Description
DISPLAY SONDE Shows information about the device such as the vendor name, model name,
SDI-12 address, protocol version, number of available measurements and the warm-
up time.
CFG PARAMETERS Gives a name and measurement unit to the SDI-12 channel. Each channel is initially
shown with a generic reference indicator in the same order that is set in the
SDI-12 device. Table 2 shows the measurements that are supported by the controller.
Note: It may be necessary to configure the SDI-12 interface for the sonde.
SCAN INTERVAL Sets the time interval when measurement data is refreshed in the controller. Short
time intervals decrease the battery life.
