Selecting and using batteries:
The FracSim meter uses a switching power supply and can accept
battery voltages from 6.5 to 20 volts. The higher the voltage, the less
current it draws due to the switching power supply. Using the
supplied battery holder you can use 2 X “9V. Alkaline batteries work
but can be substituted with "9V"rechargeable batteries.
The battery voltage is momentarily displayed when the meter
powers up. The Battery voltage dictates the maximum voltage on
frequency simulate and current sourcing modes.
To open the battery compartment remove the 4 screws on the
bottom of the meter. This will release the battery cover. Disconnect
the connectors on the top of the batteries to remove them from the
meter. Avoid contacting the battery pack connector terminals
incorrectly with the battery pack terminals (reverse polarity). This
has been tested and does not cause immediate damage but is not
recommended.
Cold weather operation:
In colder weather (less than 0˚C), the meter should be powered up
inside before being exposed to the colder weather. The FracSim
meter is calibrated at 22˚C, the highest level o accuracy is at 22˚C
(the temperature where it was calibrated at).
Fail Safe Contrast boot:
If the meter's displays contrast is far out of adjustment you can
power up the meter in a special mode to set the contrast. Follow
these steps: Power on the meter by pressing the button but continue
to hold down the button. The meter will beep a pulse beep for about
7 seconds. when the beep turns into a continuous tone release the
button. the meter will now change contrast slowly. When the text
becomes clearly visible press the button again to set

Warnings:
Do not open the case:
Opening the case beyond the battery compartment will void
warranty. There are no user serviceable parts. The current measure
has 1 0 ohm’s resistance with a PTC and cannot be damaged even
with a dead short (maximum 0 volts).
●30 VDC MAX.
● NOT INTRINSICALLY SAFE.
● DO NOT APPLY THE CURRENT SOURCE OUTPUT OF
THE FRACSIM METER TO THE GND OF ANOTHER
VOLTAGE SUPPLY, THIS MAY GENERATE A HIGHER
VOLTAGE DUE TO THE SERIES EFFECT AND
DAMMAGE THE FRACSIM METER.
● BE AWARE OF THE ACCURACY SPECIFICATIONS OF
THIS DEVICE. PLEASE REFERENCE THE SPECS AND
MAKE SURE THEY ARE WITHIN YOUR TOLERANCE.

Using this manual:
When using the manual please note the following:
Using the interface turn knob:
To become efficient and fast at managing the meter you should take
a few minutes to learn the correct interface turn knob usage.
The turn knob is a rotary encoder. By turning it left and right you
can scroll through different menus and adjust variable set points.
By pressing the turn knob down you can; power the meter off and
on, select menu items and exit from menus.
Pressing the turn knob down and holding or 1 second will
power the meter on.
Pressing the turn knob down and holding or 2 seconds will
power o power o .
Pressing the turn knob down and holding between 1 and 2
seconds causes the meter to exit the current mode
This icon marks all the pin outs for each function. All
measurement function use the "Red Socket"
(positive)" and "Black socket"(negative)"
This icon marks important operation functionality.
Please keep these in mind when using the FracSim
Meter.

Voltage Measure:
The FracSim meter will measure -30V to 30 V DC. To access voltage
measure mode from the main menu select MEAS<= and V DC .
Pressing the turn knob down quickly will change the range to
-1500 mV to 1500 mV and back
Current Measure:
The FracSim meter will measure -21mA to 21mA. To access current
measure mode from the main menu select
MEAS<= and mA .
The current measurement circuit does not employ a traditional
use or protection. Current limiting is accomplished by utilizing
a relatively high internal resistance, 100 ohms. The current
measure was designed or use on current loops and in most
situations this load is ine. Just be aware o its limitations.
If the FracSim is exposed to a dead short on current measure the
internal PTC will open up however some current will still flow and
the display will flash OL.
Continuity Measure:
The FracSim meter will measure continuity. An audio and visual
feedback will trigger at approximately 50Ω To access continuity
measure mode from the main menu select
MEAS<= and Ω .
10
iode Measure:
The FracSim meter will measure voltage drop across a diode. To
access diode measure mode from the main menu select MEAS<=
and DIODE .
Frequency Measure:
The FracSim meter can measure frequency from 1 to 10000 Hz @ 0.5
to 30 volts AC/DC. To access frequency measure from the main
menu select
MEAS<= and Hz.
The measure frequency function also displays the duty cycle, and
Min and Max peak values.
Pressing the turn knob down quickly will change the meter to
Scope view
Scope View:
Once inside the frequency measure mode pressing the turn knob
quickly will enter the Scope View mode. The Scope View mode
display a visual representation of the frequency signal. The time base
and voltage level is auto ranging.

Current Simulate Functions:
The FracSim meter can sink or source 0 up to 22mA while
simultaneously measuring loop voltage. To access the current
simulation from the main menu select SIM=> and mA. Use the
following pin outs:
As previously stated the current simulation also shows the measured
loop voltage for quick loop diagnostics. The loop voltage function is
only useful while sinking current. Most transmitters require a
minimum 8 to 10 volts. So if you see a loop voltage lower than this
or the transmitters recommended voltage minimum, then this is an
issue. The FracSim meter will work because it is internally powered
but the transmitter may not
Pressing the turn knob down quickly will increment the
output value by 4mA each press
Turning the turn knob clockwise will increment the output
value by 0.1mA
Turning the turn knob counter-clockwise will decrement the
output value by 0.1mA

Frequency Simulation Function:
The FracSim meter will simulate an AC / DC square wave frequency
from 1 to 5000 Hz with a range from 0 to 18 volts (maximum is
proportional to battery voltage). To access the frequency simulation
from the main menu select
SIM=> and Hz. Use the following pin
outs:
Adjustments:
De ault output is 18V (battery voltage) DC coupled at 100 Hz
Turning the knob will increment / decrement the requency
output
Pressing the turn knob down quickly will enter an adjustment

First Select AC or DC or the correct type o coupling
Second turn the knob le t and right to adjust the voltage level
For devices that have a very low level switching point use the
AC mode. An example o a low level input could be the Red
Lion silver tube ampli iers (Part: ASTC0000).

Serial ata Functions:
The FracSim meter can read and write RS 485 ASCII data @4800,
9600, 19200, 38400, 57600. The data output can either by in WITS or
CSV format. Every time data is received the FracSim will beep. To
access frequency measure from the main menu select
RS485 .
There are several serial data modes here is basic list of when to use
each:
DAT <= , RAW - use when you need read generic ASCII
data.
DAT <= , COMPANY SPECIFIC - use when you need read
application speci ic data.
DAT => , CSV - use when you need output CSV ormat ASCII
data.
DAT => , COMPANY SPECIFIC - use when you need to
output application speci ic data.
DAT <= , RAW
Select the baud rate. Once inside the data window you will see
incoming data. If you see "waiting on data" it means no valid data
has been received. The maximum input is 500 characters per data
burst. Turn the turn knob to scroll through the data buffer.
DAT <= , COMPANY SPECIFIC
The baud rate and format is pre determined. The data input is
application specific. The display shows the data input with the
corresponding channel names. Turning the turn knob will scroll
through all the data available.
