1Installation and operating instruction
PM-Progress is designed for accurate measurement and display of all major electrical and power quality
parameters, in single-phase two wire, and three-phase three and four-wire system configurations.
This manual provides all the necessary instructions to safely install and operate the instrument. For more
information please contact your distributor.
1.1 Measurement
In measurement mode, the buttons control the displayed measurement as follows:
Used to select the Voltage and Frequency
display screens.
In set-up mode this is the “Back” button.
Used to select the Current display screens.
In set-up mode this is the “Up” button.
Used to select the Power and Power Factor
display screens.
In set-up mode this is the “Down” button.
Used to select the Energy display screens.
In set-up mode this is the “Enter” button.
Table 1 - Measurement
1.2 Setting up
Press and hold the two buttons and simultaneously for five seconds until the password
screen is displayed.
Press four times to enter the default password of “0000”.

The system setup screen will be displayed on the screen. Press the button to scroll down the
menu until you see the CT primary setting screen.
Press the button to enter the CT primary setting screen. The first digit should start flashing.
Use and buttons to set the digit to the required level then press to confirm. Repeat
this process until all four digits have been set to the desired CT primary value. (e.g. 100A = 0100A,
1000A = 1000A).
The word “SET” should be displayed after the fourth digit has been entered to confirm that the
primary CT value has been set.
Press to return to the first level menu structure, to scroll up and down the structure to adjust
other parameters (if needed). If no other settings are required, press to exit set-up mode and
return to measurement mode.
1.3 Setup menu structure
Change password:
nnnn - 4-digit number –default ‘0000’
Supply systems:
3-phase (3 or 4-wire) or Single phase
CT:
Set maximum current that can be monitored according to CT in use. nnnn –4-digit number 0001 to 9999.
Demand Interval Time:
Selects demand time in minutes from 60/30/20/15/10/8/5/OFF.

Import from output module 2
Rate 0.1/1/10/100/1000 kWh or kVArh per pulse
Pulse width 200/100/60 ms.
Energy:
kilo/Mega
Test:
Phase sequence
Display on –all elements on to check display
Display toggle - Each element is turned on and off
SOFT:
Displays software version number.
1.4 Menu option selection
After entering the correct password, use and buttons to navigate up and down the first
level until the desired parameter is reached. Selection does not roll over from bottom to top of list
or vice versa.

Press button to select the desired parameter and enter the second level menu structure.
If an item flashes, then it can be adjusted by and keys. If not, there may be a further layer,
e.g. Comms - Baud rate, before adjustment is possible. Press to select the lower layer.
Having selected an option from the current menu layer, press to confirm your selection. The
word SET will come on.
Once all the necessary selections have been made and the required settings entered, press to
return to the first level menu structure. The word SET will turn off and you can then use
and keys for further menu selection.
On completion of all settings, press repeatedly to exit set-up mode and return to measurement
mode.
