‘DIAMOND GRAPH‘ DISPLAY MODES:

'GRAPHIC MODE 1' (ABSOLUTE EGT): Press 'BUTTON 1' once (if in GRAPHIC MODE
1) to activate. All four graphs in the upper area come on and display absolute EGT
temperature. This mode is most useful to spot plug / injector or valve problems. Each bar
50 deg. F with the base beginning at 1300 deg. F.

'GRAPHIC MODE 2' (RELATIVE EGT MODE) Press 'BUTTON 1' again (if in GRAPHIC
MODE 2) to activate. All four graphs, plus two brackets, in the upper area come on and
display RELATIVE EGT temperatures. This mode is most useful to watch short-term
behavior of EGT to spot plug / injector or valve problems or when leaning to peak EGT.
Each bar 20 deg. F with the bases normalized when the mode was activated.

DIGITAL DISPLAY MODES:

The digital displays shows individual temperatures for EGT and CHT. Periodically
messages such as '

E1 C1

' appear to show which probes you are viewing digitally

(ex.1: '

E1 C1

' means '

E

'GT

1

and '

C

'HT

1

are in view; ex. 2: '

P1 H4

' means '

P

'eak

EGT

1

(hottest) and '

H

'ottest CHT 4 are in view).

The digital display defaults to the hottest CHT. For example, if CHT 1 is the hottest, the
digital display will show H1 periodically. Pressing button 2 will cycle through each CHT
and the hottest and allow you to select a different CHT by choosing C1, C2 etc. After
the unit is turned on, the digital display defaults to show the hottest CHT. Temperature
is displayed in Fahrenheit units.

Additionally, warning messages are shown if a cylinder has reached 'red line'
temperature (ex: '

H2

' for hot cylinder 2), or is being 'shock cooled' (ex: '

C3

' for cold

cylinder 3).

You can select a digital view by successively pressing 'BUTTON 2' :

After powering up the unit, the EGT digital display defaults to EGT 1 Periodically the
digital display will identify which EGT you are seeing by showing and E followed by the
EGT number, such as E1 for EGT 1. After you have successfully leaned the engine (as
an example, lets assume it was EGT 2), the digital readout is locked to that EGT and E1
will change to P2 signifying that it

eaked on EGT 2. Tap button 2 to select a different

EGT by choosing E1, E2, E3 etc. (Note: not available when in the peak mode).
Temperature is displayed in Fahrenheit units.
