IKA RET Control Visc

PyLabware driver for IKA RET Control Visc stirring hotplate.

class PyLabware.devices.ika_ret_control_visc.RETControlViscHotplate(device_name, connection_mode, address, port)

Bases: AbstractHotplate

This provides a Python class for the IKA RET Control Visc hotplate based on the english section of the original operation manual 20000004159 RET control-visc_042019

Default constructor.

Parameters:

• device_name (str) –

• connection_mode (str) –

• address (str | None) –

• port (str | int) –

check_errors()

Not supported on this device.

clear_errors()

Not supported on this device.

get_ph()

Gets pH value from external probe. Returns value around 14 with no probe connected.

Return type:

float

get_safety_temperature()

Gets safety temperature sensor reading.

Return type:

float

get_safety_temperature_setpoint()

Gets safety temperature sensor setpoint.

Return type:

float

get_speed()

Gets current stirring speed.

Return type:

int

get_speed_setpoint()

Gets desired speed setpoint.

Return type:

int

get_status()

Not supported on this device.

get_temperature(sensor=0)

Gets the actual temperature.

Parameters:

sensor (int) – Specify which temperature probe to read.

Return type:

float

get_temperature_setpoint(sensor=0)

Gets desired temperature setpoint.

Parameters:

sensor (int) – Specify which temperature setpoint to read.

Return type:

float

get_viscosity_trend()

Gets current viscosity value.

Return type:

float

get_weight()

Gets weight - the hotplate has embedded weight sensor.

Return type:

float

initialize_device()

Resets the device.

is_connected()

Checks whether the device is connected.

Return type:

bool

is_idle()

Returns True if no stirring or heating is active.

Return type:

bool

set_speed(speed)

Sets the stirring speed.

Parameters:

speed (int) –

set_temperature(temperature, sensor=0)

Sets desired temperature.

Parameters:

• temperature (float) – Temperature setpoint in °C.

• sensor (int) – Specify which temperature probe the setpoint applies to.

setup_watchdog_mode2(temperature, speed)

This can be cleared remotely

Parameters:

• temperature (int) –

• speed (int) –

start_stirring()

Starts stirring.

start_temperature_regulation()

Starts heating.

start_watchdog_mode1(timeout)

This can’t be cleared remotely, requires power cycle.

Parameters:

timeout (int) –

start_watchdog_mode2(timeout)

This doesn’t display any error as advertised in the manual, just falls back to safety values

Parameters:

timeout (int) –

stop_stirring()

Stops stirring.

stop_temperature_regulation()

Stops heating.

stop_watchdog()

Clears mode2 watchdog.
