How to Operate the Instrument 12.1. Configuration System The instrument is fully configurable from the 3 push button keypad a the 4 red digit led display at the front of the instrument (see Table 6).
• key ‘LE’ () activates the ‘messages’ function (see section 12.5). ‘ECO’ FUNCTION (‘DISPLAY’ POWERED OFF) The ‘Eco’ function powers off the display under the following conditions: • the instrument is in ‘normal mode’ of operation. • there is no interaction from the operator for 60 seconds. The decimal point remains active (flashing), indicating that the instrument is working correctly.
12.4. How to Operate the ‘Force’ Menu HOW TO ENTER THE ‘FORCE’ MENU With the instrument in ‘normal mode’ of operation (see section 12.2), press and hold the ‘UP’ () key for 1 second. The horizontal LEDs light from bottom to top. When the upper led lights, the instrument enters into the ‘force’...
12.5. How to Activate the ‘Messages’ Function HOW TO ACTIVATE ‘MESSAGES’ FUNCTION With the instrument in ‘normal mode’ of operation (see section 12.2), press the ‘LE’ () key to activate the ‘messages’ function. The ‘messages’ function displays information about the instrument. The information available is configurable (see section 16.8).
13.2. V AC Frequency Signals SIGNALS ACCEPTED The instrument has a dedicated input to read frequency from voltages up to 600 V AC and voltages up to 60 V AC. Phase-to-phase and phase-to-neutral connections are accepted. PREDEFINED CONFIGURATION CODES See ‘Table 2’ for a list of predefined configuration codes for input-output signal ranges. To activate a code see section 16.1.

15. Frequency Calculation Modes The instrument calculates the frequency applying the ‘slow’ mode or the ‘fast’ mode. Fast mode ‘Fast’ mode activates when the ‘input high signal’ parameter (see section 16.5) is higher or equal than 500 Hz. The frequency calculated is the number of impulses received during a time window, divided by the time window value in seconds.
16. Configuration Menu 16.1. Function Codes and Sensor The fastest way to configure the instrument, is to select a predefined configuration code (see Table 2) and a predefined sensor (see Table 3). At the ‘Configuration code’ (codE) parameter use keys ‘UP’ () and ‘LE’ () to move up and down through the list of codes.
16.2. Sensor Configuration Sensor configuration is a critical part of the configuration. If the sensor is correctly configured, the instrument will be able to read impulses. If the sensor is not correctly configured, the instrument will not be able to read any impulse signal and it will be considered a 0 Hz signal.
At the ‘Gate’ (GAtE) parameter configure the value to ‘0.25’, ‘0.50’, ‘1.0’, ‘2.0’ or ‘4.0’ seconds. Applies only in ‘fast’ mode (see section 15). At the ‘Time to 0’ (tt0) parameter configure a value between ‘1.0’ and ‘10.0’ seconds. Applies only in ‘slow mode’...
16.4. Output Range At the ‘Output range’ (out) menu entry, select the output signal range to 4/20 mA (value ‘420’) or to 0/10 V DC (value ‘010’). The output signal range selected can be later customized to operate in a reduced range of signal (see section 16.5).
16.6. Display Information At the ‘Display information’ (dISP) menu select one parameter to read on display when the instrument is in ‘normal mode’ of operation. If you need access to more than one information, see the ‘messages’ function (see section 16.8) associated to front key ‘LE’ ().
16.8. Key ‘LE’ (‘Messages’ function) The key ‘LE’ () at the front of the instrument gives access to a configurable set of information messages. At the ‘Key LE (messages function)’ (K.LE) menu, select the informations to be displayed when the front key ‘LE’ () is pressed (see section 12.5).
16.9. ‘Tools’ Menu The ‘Tools’ (tool) menu groups several functions. • at the ‘Eco mode’ (Eco) parameter, define the time to wait before the display is powered off (while in ‘normal mode’ of operation). Default value is 60 seconds. Configure ‘0’ to disable the function and maintain the display always on.

value, are treated as a ‘0’. This parameter applies to all measuring ranges. • the ‘Version’ (VEr) parameter informs about the firmware version running in the instrument. • at the ‘Password’ (PASS) parameter define a 4 digit code to block access to the ‘configuration menu’. Activate the password to prevent access to the instrument configuration by non authorized personnel.
Full Configuration Menu Press ‘SQ’ () for 1 second to access the ‘configuration menu’. For a description on how to operate inside the menus see section 12. For a full vision of the ‘configuration menu’ structure see section 16. Full Configuration Menu...
