TC-1 Operating Manual
Page 8
Only “EGT SETUP” is shown below, follow the same steps for CHT setup.
Move the highlight over this menu option and press the rotary button to return to the “TC Setup”
menu.
Select the number of EGT or CHT channels you want to use. Choices are from 1 to 4. The
temperature display will configure itself to make best possible use of the available display size.
Please note that the minimum number of EGT & CHT channels that can be displayed is 1 and the
maximum number of EGT and CHT channels that can be displayed is 4.
A selection between “HIGHEST” or “SCANNING” can be selected. If “HIGHEST “is selected then the
current highest thermocouple temperature is displayed. If “SCANNING” is selected then the E-3 will
cycle through each thermocouple channel highlighting it as well as showing its temperature.
This function sets the top end of your temperature bar graph. It has no effect on the actual
temperature range that can be displayed in the digital temperature readout. Select the range to be
just higher than the highest temperature you expect to measure using this channel.
Select this function to “ON” if you want the bar graph display to show the upper half of the
temperature range only. This results in a higher resolution of the temperature range you may be
interested in. For engine temperature measurements we recommend that you set this to “ON”.
Adjust the temperature that you would like to use as an alarm limit. Any temperature above this limit
will activate the alarm. Active alarms will flash the affected channel and also activate the alarm
contact that you can use to switch a lamp on.
Select whether you want to turn the alarm on or off. To avoid false activation of the alarms, the
alarm function is only activated 10 seconds after the instrument has powered up.
Select if you are using a K-type, J-type or E-type thermocouple probe for this channel. All probes
supplied by MGL Avionics are K-Type. J-types are sometimes used with American made CHT
probes. All EGT probes are K-type. E-type probes are seldom used.
