
Example 3: Display 1234567,8 GJ => pulse value for energy pulse output = 0,1 GJ/pulse
13.5.2 Pulse output for volume (OUT2-Volume)
One pulse is generated by the pulse output for volume when the second-to-last digit of the volume display is
increased by one.
The pulse value is automatically determined by the second-to-last digit of the volume display. The pulse units are
identical to the units of the volume display.

Example 1: Display 12345,678 m
3
=> pulse value for volume pulse output = 0,01 m

/pulse

Example 2: Display 12345678 l => pulse value for volume pulse output = 10 l/pulse
13.5.3 Pulse outputs for calculator with combined heat/cooling measurement
For this type of calculator the outputs OUT1 and OUT2 are both outputs for energy.
The behaviour is the same as described in chapter 13.5.1.
OUT1 is the output for the pulses for heat energy.
OUT2 is the output for the pulses for cooling energy.

14 Information Messages
When the instrument has detected an information message, the message symbol is displayed:
The specific message can be found at the menu item 8 ‘Information message’ in Level 1/Main loop (see section 10
“Display”).
The instrument recognizes seven message causes, which can also occur in combination with each other. The
messages are shown on the display. The message code is displayed alternately in binary and hexadecimal form.
