To activate Energy AnCal:
To move the cursor to the [Energy AnCal] menu cell press
Press to enable numeric entry. Note that an equal sign (=) appears before number.
Type the desired flow rate using current rate units (e.g., 10.00 MBTU/H). Note that the [Energy
Rate] menu cell now reflects the artificial rate.
To move the cursor away from the menu cell press to turn Energy AnCal off.
2.11.4 FLOW DATA MENU
This menu provides a “live” display of all flow-related output data.
2.11.3 ENERGY AnCal
This menu cell allows you to enter an artificial energy rate in current rate units that will drive the meter’s
analog outputs, energy totalizer output and the display screen shown below. You can use AnCal to check
the analog outputs or as a reference source for calibrating external devices such as remote display
screens or chart recorders and RTU’s. To test the Totalizer function, leave Energy AnCal active long enough
for an accumulation to appear on the diagnostic data screen shown below. Moving the cursor from the
menu cell cancels the AnCal function.
NOTE: AnCal remains active only while you remain in this menu cell.
ENERGY DATA MENU ITEMS
Energy Rate This is a real-time (updated) energy rate display in current rate units (e.g.,
MBTU/H).
Energy Total This is a real-time (updated) energy total display in current total units (e.g.,
KGAL).
Ts, Tr, Td Real-time (updated) supply, return and differential temperature of the RTD’s
servicing this channel.
CE Method This is a real-time Chiller Efficiency display in current rate units (e.g., kW/ton).
Only used with units that have Analog Input capability.
Energy AnCal Energy Rate Simulator for calibrating external devices, etc. Highlight this item
then press the <Right Arrow> to enable numeric entry. Type desired simulated
energy rate. Be aware of the units prefix (K, M, etc.).

Energy Data
Note that the [Energy
Rate] menu cell
immediately reflects the
Energy AnCal entry. Over
time, the Energy Total
display will also increase.
