Basic Unit
OM-VLT
Temperature Data Logger with Built-In Printer
Model OM-VLT is a programmable
temperature data logger, strip
recorder and alarm device with
integral digital display. The easy to
follow menu driven programming
is done via the front panel keys.
The unit records, saves and prints
up to 290 temperature readings at
predefined intervals. The OM-VLT
produces an alarm when the
temperature goes out of the
defined range or after the
temperature remains out of range
for a certain period of time. The
OM-VLT prints temperature data
directly via the integral printer and
can also send temperature data to
an external PC. Communications
with a PC is done by using
Windows Hyperterminal software
so no additional software is
required. The OM-VLT can also
send alarms to an external device
via the built-in relay contact.

Alarms: High and low temperature,
end of paper, no sensor; audible
(internal buzzer)/visual (alarm
LED)/normally open relay contact
Audible Alarm (Internal Buzzer):
Some alarms trigger the internal
alarm buzzer. The buzzer can be
silenced by pressing EXIT on the
front of the data logger or by
connecting the optional remote
buzzer silencer switch (OM-VLTSK) which momentarily shorts the
buzzer silencer contacts on the data
logger. The alarm buzzer can also
be enabled or disabled via the data
logger front panel menu
programming.
Temperature Alarm Operation:
If the measured temperature goes
outside the maximum or minimum
temperature limits for an amount of
time equal to the defined alarm
delay period (if any), an alarm is
sent – the internal buzzer sounds
(if enabled), an alarm is sent to an
external device via the alarm relay
contact (if enabled) and the alarm
LED lights.
Disconnected Temperature
Sensor Alarm Operation: If the
temperature sensor is disconnected
the display shows the message
nOS, the alarm LED lights and the
internal buzzer sounds (if enabled).
