MTEK6000 SERIES USER'S MANUAL

Assigning Function Keys

In configuration mode, any parameter can be assigned to a function key. To assign a function key:

1.Enter configuration mode by pressing conf (use the password, if required).

2.Display the desired parameter. Press jump followed by the address of the parameter, and then press ent (see Appendix A for parameter addressing for your device).

3.Assign a function key to the parameter. Press jump, edit, and then the function key you wish to assign to the current item [F0 - F9].

NOTE

There are pre-defined function keys for your device - see Appendix A.

Audit Trail

The MTEK6000 maintains an electronic audit trail file that records all parameter changes and calibrations performed on the unit. Each entry is identified with the date and time the event occurred. The contents of this file cannot be changed, providing a secure, non-editable audit trail.

In the standard MTEK6000 configuration, the audit trail is disabled. You can enable audit trail logging using Metretek, Inc. software or editing the Audit Trail Enable/Disable parameter to 250 using the keypad and display.

NOTE

Once the audit trail is enabled, it cannot be disabled without downloading a new database with this feature disabled.

Once enabled, the device maintains the audit trail file with a maximum of 250 records. You can upload the information from the unit to a portable or host computer using

3-8

Metretek software. Once the audit trail is full, the device will not allow any other changes to parameters; the audit trail must first be uploaded and reset by the host software.

Wake-Up on Pulse (Event Driven)

The MTEK6000 EFC employs a wake-up on pulse (event driven wake-up) mode in which the unit can be configured to wake-up on a specified number of pulses (meter revolutions). During wake-up, pressure, temperature, and the rest of the analog channels are sampled, and the unit executes the processes and run calculations.

In this mode, the EFC should be configured to wake-up on the number of specified pulses along with an hourly wake-up to record history data. See Appendix A for the address of the Wake Up On Pulse (event driven) and Wake Up Interval (Seconds) parameters.

Analog Sampling

The MTEK6000 has the ability to sample the dynamic analog input variable channels at intervals from 1-99 seconds. Once enabled, the unit samples pressure, temperature, case temperature, and the external 1-5 volts or 4-20 ma channels once for each selected interval.

NOTE

Battery voltage is NOT sampled at this rate.

The sample’s minimum and maximum values are then checked against their corresponding High and Low Setpoints. If the device determines these conditions were exceeded, it “wakes up” and finds the average of all samples accumulated since the last process execution, displays this analog mean, and applies it to any necessary calculations. To enable, set Analog Sampling Rate parameter to 1-99 seconds.
