6. To set the totalizer to zero for a configured flow channel, select Reset.
Note: If channels are added to or removed from a program, the instrument erases all data from all channels
and totalizers (resettable and non-resettable). Make sure to download the data from the logger to a safe
location before the program is changed.
Configure the mechanical totalizer
Pre-requisites: Connect the mechanical totalizer to the instrument. Program the instrument to record
a flow channel in the data log.
The mechanical totalizer is an external device that counts the total flow volume for one flow channel.
The user cannot set the mechanical totalizer to zero after operation starts.
1. Push MENU .
2. Select Totalizers>Mechanical.
3. Select the options:
Option Description
Enable/Disable Starts or stops the totalizer.
Unit Sets the totalizer flow units. Options: gallons (default), liters, acre feet, cubic feet, cubic
meters.
Source Selects the sensor or input with the applicable flow channel.
Volume Per Pulse Sets the flow volume for each pulse signal from the flow channel, for example
100 gallons. Set the flow volume to a large number for high flow volumes and a small
number for low flow volumes.
Pulse Width Sets the time (in ms) that each pulse signal operates from the flow channel.
Pulse Delay Sets the time (in ms) between each pulse signal from the flow channel.
4. Calculate the total flow for a time period.
a. Record the number on the mechanical totalizer at the start of the time period.
b. Record the number on the mechanical totalizer at the end of the time period.
c. Subtract the number at the start of the time period from the number at the end of the time
period to get the flow volume in pulses.
d. Multiply the flow volume in pulses by the volume per pulse to get the flow volume in the
selected flow units.
Configure the inputs and outputs
Use the I/O menu to configure the inputs, outputs and relays in the instrument or in the external
IO9004 module.
1. Push MENU.
2. Select Hardware Setup>I/O.
