Easy to use
The Transmation CheckMate 300 will check, calibrate
and measure all the industrial frequency devices in your
plant. Three ranges cover most instrumentation frequency
signals.
Source frequency
Calibrate flowmeters, variable speed drives, computer
inputs or any other instruments that measure frequency.
Easily set any value with the intuitive UP and DOWN
pushbuttons. Separate buttons for each digit make
adjustments fast and easy.
The CheckMate 300 is easy to use. Select a frequency
range and use the decade push-buttons for the precise
output you need.
Recall output settings
The “QUIK-CHEK” pushbuttons provide rapid checking of
any three points in each range. Quik-Chek settings
remain in memory even when the CheckMate 300 is
powered off.
Measure DC voltages
Check flow sensor, turbine and integrator outputs. The
CheckMate 300 measures up to 1000 CPM, 1000 Hz and
10.00 kHz.
Display the present reading, maximum or minimum by
pressing the READ, MAX or MIN pushbuttons to quickly
check how much the loop has varied or the stability of
control.

Turn-on
Each time you turn on the CheckMate 300 the
LCD will display all segments for about 1 second.
It then displays the most recently selected source
or read setting.
Source
The three Quik-Chek outputs will be the same as
previously stored. Each time a different function is
selected, the three Quik-Chek outputs will be
recalled.
Read
The CheckMate 300 is ready to measure the
same signal as the last time it was turned on and
will automatically update the MAX & MIN readings
for recall at any time.
Selecting ranges
For some functions there are two or more ranges
or scales. Press the RANGE/TYPE pushbutton to
scroll through the ranges and scales. The ranges
will scroll and will go back to the beginning after
the last choice.
Turn-off
Press the POWER push-button to turn the
CheckMate 300 off. If AUTO-OFF is enabled, the
Checkmate 300 will turn itself off after 30 minutes
of inactivity.
Autocal
To maintain accuracy, the CheckMate 300
periodically recalibrates its measuring circuitry
against internal references. While this is occuring
the word CAL will appear on the display for less
than 2 seconds.
Changing batteries
Low battery is indicated by BAT on the display.
Approximately four hours of operation remain
before the LCD blanks and CheckMate 300 shuts
itself down. Turn the CheckMate 300 off, loosen
the captive screw securing the battery
compartment and lift off the cover from the bottom
of the case. The four “AA” batteries are easily
removed and replaced (alkaline supplied and
recommended). Replace the battery compartment
cover and tighten the screws.
Auto-off
CheckMate 300 can be set up to turn itself off
after 30 minutes of inactivity. The internal timer is
reset to 30 minutes each time a pushbutton is
pressed. This configuration is part of the Default
Settings below.
Default settings – Auto-off
CheckMate 300 may be restored to the factory
settings. This will reset the HI and LO “Quik-Chek”
memories. Prompts also guide you for selection of
Auto-Off.
1) Press and hold the STORE/RESET push-
button while turning the CheckMate 300 on.
2) Keep pressing the STORE/RESET push-button
until the display flashes (about 5 seconds) then
release.
3) The words BAT and ON will appear on the
display indicating that AUTO-OFF is selected.
4) To toggle the AUTO-OFF function on and off
press the RANGE/TYPE push-button and the
words oN and oFF will display.
5) After five seconds the CheckMate 300 will
automatically store your choice and the
CheckMate 300 will begin normal operation. Or
you may press the STORE/RESET button to
accept your choice and begin operation.

Source frequency
Select source by pressing the SOURCE/READ
pushbutton until the word SOURCE appears on the
LCD display. To change the output value press the
UP or DOWN pushbutton corresponding to the digit
being displayed. To ramp the output press and hold
any UP or DOWN pushbutton. The display will
continue to change in increments corresponding to
the digit being changed and will automatically carry
up and down until the limits of the range are
reached. This function operates in all three output
positions (HI, SET & LO).
Storing Quik-Chek outputs
1) Press HI or LO
2) Press the UP/DOWN keys to desired value
3) Press the STORE push-button
The LCD will flash once to show that the value
was saved
If a value is in the SET position and you want that
value stored in HI or LO, press and hold the STORE
push-button, then press the HI or LO pushbutton.
The display will flash once to indicate the value has
been stored. Then release both pushbuttons.
Recall Quik-Chek outputs
When you need a stored value just press the HI or
LOW Quik-Chek pushbutton. Any value for the
selected range may be stored in HI & LO. The
CheckMate 300 remembers the HI, LO and SET
values for each function with the power on or off.
Each time a different function is selected, the last
three Quik-Chek values for that function will be
recalled.
Note: The same value is stored for both mA and %.
The recalled value will be displayed in the units you
have selected.
Open loops
The digits on the LCD will flash if there is an open
loop or if the polarity is reversed. Check all the
connections in the loop or try reversing the leads.
Read milliamps
Select read by pressing the SOURCE/READ
pushbutton until the word READ appears on the
LCD display. The READ functions measure the
desired signal.
Min/Max
To read the maximum or minimum input since read
mode was entered, simply press the MAX or MIN
pushbutton. The value will appear on the LCD along
with the word MAX or MIN. The MAX/MIN values
are automatically updated and may be viewed at
any time without disturbing the other values.
Restarting Min/Max
Pressing the STORE/RESET push-button will cause
the CheckMate 300 to store the present reading into
the MAX and MIN memories. Upon releasing the
STORE/RESET push-button the CheckMate 300 will
resume reading the input and update the MAX &
MIN values as the measured signal changes.

Signals above or below those available for the
currently selected range will be indicated by Or and
Ur on the display.

Calibrate frequency inputs
Choose this function to provide pulses into frequency measuring
instruments. The CheckMate 300 output is a zero crossing square
wave from -1V to +5V amplitude. Available ranges are from 0.01 to
10.00 kHz, 1 to 1000 Hz and from 1 to 1000 CPM (Counts-Per-
Minute).
CPM is used to simulate slow frequency signals with greater
resolution. For example, 10 Hz is equivalent to 600 CPM. To convert
from CPM to H,z divide by 60. To convert from Hz to CPM, multiply by
60.
1) Disconnect one or both input wires from the device to be calibrated.
2) Press the POWER push-button then press the SOURCE/READ
push-button until SOURCE is displayed.
3) Press the RANGE/TYPE push-button until the desired frequency
range appears.
4) Connect the red lead of the CheckMate 300 to the plus (+) input of
the device and the black lead to the minus (-).
Output frequency is adjustable with the UP and DOWN push-buttons.
Span and Zero outputs are available by using the LO and HI Quik-
Chek push-buttons to recall your stored settings.
Count frequencies
Choose this function to use the CheckMate 300 as a frequency
counter. Available ranges are from 0.01 to 10.00 kHz, 1 to 1000 Hz
and from 1 to 1000 CPM (Counts-Per-Minute).
To measure waveforms with amplitudes between 1 V and 10.25 V
RMS use the low level inputs.
1) Disconnect one or both input wires from the device to be calibrated.
2) Press the POWER push-button then press the SOURCE/READ
push-button until READ is displayed.
3) Press the RANGE/TYPE push-button until the desired frequency
range appears.
4) Connect the red lead of the CheckMate 300 to the plus (+) output
of the device and the black lead to the minus (-).
Display the present reading, maximum or minimum by pressing the
READ, MAX or MIN pushbuttons.
Signals above or below those available for the currently selected range
will be indicated by Or and Ur on the display.
