M340 Manual Operation 13
4 Operation
4.1 Power ON
1. Allow the M340 to warm-up to room temperature for at least two hours after
unpacking and prior to applying power to remove any condensation.
2. Connect the power cable to a VAC service that matches the power requirement
specification noted in the Technical Data section and on the Specification Label
located on the rear of the M340.
3. Power the M340 by turning on the power switch.
The upper RED display is the current emitter temperature. The lower GREEN display is
the setpoint temperature.
Warning: Do not connect or disconnect while power is on. Do not attempt to operate
without cables connected.
4.2 Changing the Setpoint
To change the temperature setpoint (green display), Press either the or buttons
on the controller. Each press will advance the setpoint 0.1 degree. To advance faster, press and
hold for 5 seconds until it advances a few degrees/second. Let go when it is near the desired
setpoint. Press again to bring it to the exact value desired. Note that this setpoint will be
retained when power is turned off.
4.3 Power OFF
To power down, simply turn the power switch off. If the emitter was running below 0 °C, and
purge gas was not used, it is a good idea to raise the setpoint to 80 °C and let it soak for about
10 minutes prior to turning off. This removes moisture that may have built up on the emitter
and surrounding surfaces prior to shutting down. If purge gas was used, leave it on for several
minutes (10) after turning power off for the same reason.
4.4 Additional Controller Functions
The temperature controller has been factory set for optimum performance. Any attempt to alter
the set-up routines within may render the M340 inoperable. Below are some changes that you
may desire.
4.4.1 Changing Temperature Units (C-F, F-C)

2. Press until 05 appears in the lower display
3. Press 11 times until UNIT appears in the lower display
4. Press to change C to F or F to C
