IPM520 FAQ’s
Where can I find the wiring guide for my display?
Correct setup is essential to the proper function of ipm520 series meters. The back of the
meter is shown above. The picture illustrates how the location of the top connection
board (optional board) and the bottom (main) board. The diagrams below show the pin
connections for both the main and optional boards. For the main board, the power cord
will connect in pins 1, 3, and 5. Both the connections between the main board-power
supply and the main board-sensor are shown in the diagram. If you choose to use
Channel 1, the signal wires (on sensor) will connect to the Channel 1 input pins, and the
Excitation wires will match up with the Excitation pins. For Dual Channel systems, if
Channel 2 is preferred the signal wires will connect with pins S and 13. For the D525 and
the D528 (meters using the RS232 connection) there is an optional additional connection
between the meter and a PC unit (see the RS232 Manual).

What do the buttons on the display do?
For the IPM520, see “Front Panel Keys” and “Setup Mode Key Function” starting on
page 10 of the Product Manual.
For the IPM525, see “Front Panel Keys” and “Setup Mode Key Function” starting on
page 8 of the IPM525 Manual.
What does each menu item do?
CHAn Under this menu it is possible to choose the desired channel to program for
reading input. Here it is also necessary to choose the setup routine and
calibration method for individual channels.
OutPut Under this menu both alarms and analog output can be set up.
DiSPLY Under this menu update rates, filter and snap functions are programmed.
SPEC This menu allows for the setup of special functions. Here the individual F keys
are programmed, remote R1-R4 inputs are setup as well as linearization, peaks,
access codes, and default settings.
How do I change the numbers in the menu functions?
See “Programming Tips” on page 15 of the Product Manual and IPM525 Manual.
How do I setup the special features?
See “Special Features Programming Brand” on page 24 of the Product Manual and
IPM525 Manual.
How do I setup the remote input?
Remote inputs allow the user to control specific functions of the meter through the use of
input buttons and switches. In the SPEC menu there is the option to set the remote inputs
(,b>r in 1 - r in 4). By setting Remote Input #1 as a peak then a button/switch (#1) will
control the peak function. The diagram below shows the connections for the Remote
Input #1. The switch/button is wired between the +Excitation and the External Input #1
port. It is also necessary to use a jumper to connect the -Excitation and the External Input
Common. The connection of additional remote inputs is done the same way. To connect
External Input #2 a button/switch would be wired between pin 9 and 12 with the jumper in

the same place. Once the connections are complete it is necessary to program the
remote inputs. The second diagram below shows the placement of the remote input pins
1-4, as well as the positive and negative excitation.
Remote Input #1 Connections
General Remote Input Connections
To set the Remote Input #1 as a Peak (all inputs are programmed in this same fashion)
enter the SPEC menu and scroll to "r in 1", press ENTER, then scroll to "PEAK 1" and
press ENTER. The pages/instrguide will then jump back to the main menu. Here you can
select SPEC again to program the other remote inputs. Remote Inputs can be set to
operate any of the given functions (they are all programmed as described above):
"Alarm" Disables alarm
"Preset" Resets both peak and valleys
"tArE" Zeros display for channel being displayed
"RESEt" Resets latched relays
SCALE2 Selects second scaling to be applied ot channel being displayed
"HOLd" Freezes display and suspends measurements
"CHAn" Selects the channel programmed under "SPEC" branch Remote Inputs
to be displayed
"dEC Pt" Selects the decimal programmed under "SPEC" branch Remote Inputs to
be displayed
"LOCk" Locks out access to the SETUP programs
"nEt" Displays net value of channel programmed
"PEAk 1" Displays PEAK 1
"PEAk 2" Displays PEAK 2
How do I setup the analog output?
See “Analog Output” on page 23 of the Product Manual and IPM525 Manual.
How do I set an alarm?
See “Alarms” on page 21 of the Product Manual and IPM525 Manual.

What are the different settings for the internal jumpers?

How do I set the excitation voltage?
Using the Main (Bottom) Board:
Pins 11 and 12 on the main board are the excitation pins (shown below). Make sure that
your -Excitation wire is connected with pin 11 and that your +Excitation wire is connected
with pin 12. The second picture is of the jumper inside of the meter. The picture shows
the location of the jumper in order to obtain specific excitation voltages. The excitation
does change depending on if you have the RS232 board installed. The RS232 board is
also shown in the top picture (located to the right of the jumper) in order for you to
recognize which set of jumper selections is appropriate for your meter. Once you have
selected your excitation voltage, find it on the picture below and connect your jumper
accordingly. Once you have reassembled your meter it is ready for use.

Using the Optional (Top) Board:
On the optional board there are four excitation pins. Pins 2 and 3 are for your -Excitation
and you can use either pins 5 or H for the +Excitation (depending on the desired
excitation). If you want +10 VDC, then you simply need to attach your +Excitation to pin 5
and your -Excitation to either pin 2 or 3. However, if you desire an excitation voltage of
+5, +15, or +24 then it is necessary to use pin H for your +Excitation. When using pin H it
is also necessary to connect the jumper in the desired location for your specific voltage.
Below is a diagram of the connections and following that is a picture illustrating the
jumper positions for the various excitation voltages.
