• Type - Select this for a list of Types of totalising. Normal or Sterilisation. Normal totaliser
function is usually associated with flow monitoring applications.
Sterilisation* is where items are subjected to heat over a period of time. Each pen can
be totalised according to the Fo or Po sterilisation* function at 250 °F (121.11°C). The
Standard Reference Temperature and Thermal Resistance (Z Value) are adjustable. All
temperature limits are adjustable. Start temp, Reference temp and Z factor are all user
defined, allowing support for many different types of sterilisation applications.

• Tag - Select and enter an identifier for the pen. Up to 17 characters.
• Add to Msgs - Toggles On and Off. Select this to add a totaliser to the messages
screen. Eg. Total1: Total 1 Reset
• Units - Normal Totaliser only. This is the Units of Measurement for the totaliser. Select
and enter the units. Up to 12 characters.
• Time Factor - Normal Totaliser only. Time factor – Totaliser adds a value once per sec-
ond, so you need to Divide by this factor. For example:
If your flow meter is in units/second Time factor is 1.
If your flow meter is in units/minute, the unit will DIVIDE by the time factor, in this
case 60 – so every 1 second, 1/60th of the unit is added.
If your flow meter is in units/hour, the unit will DIVIDE by the time factor, in this
case 3600 – so every 1 second, 1/3600th of the unit is added.
• Unit Factor - Normal Totaliser only. The Totaliser adds the engineering unit from the
instrument, onto the total (after the time factor is applied). You then need to Divide by
the unit factor. For example:
If your flow meter is in litres/time and you want to Totalise in litres – there 1 litres in
1 litre, so your unit factor would be 1, so every 1 second 1/1 unit is added.
If your flow meter is in litres/time and you want to Totalise in Cubic meters – there
are 1000 litres in 1 cubic meter, so your unit factor would be 1000, so every 1 sec-
ond 1/1000th of a unit is added.
• No Backflow - Normal Totaliser only. If the flow reading should go into a negative value,
eg. The flow meter has been switched off, and "No Backflow" is inactive, the totaliser
will subtract from the total value. When "No Backflow" is active any negative values are
ignored and the total value is held while the flow meter is off until the backflow level is
exceeded.
• Backflow Level - Only active when No Backflow is set. Set the level at which totalising
will stop if the signal flow goes below this limit and if the No Backflow option is active.
• Restrict Range - Normal Totaliser only. Toggles On and Off. When active the totaliser
restarts at Min range once it reaches Max range.
• Min. Range - Normal Totaliser only. Only available when Restrict Range is active.
Select and enter the minimum limit for the totals to range to.
• Max. Range - Normal Totaliser only. Only available when Restrict Range is active.
Select and enter the maximum limit for the totals to range from.
• Use Remainder - Normal Totaliser only. Only available when Restrict Range is active.
Toggles On and Off. If the total exceeds the maximum range set, the total will reset to
the minimum range set. When Use Remainder is active, it will carry over any amount in
excess of the maximum range set.
