Installing the probe
1) Turn the power off.
2) Connect the K-type thermocouple probe to the channel to
be used. Hold the connector and insert the plugs all the
way into the terminals with the correct polarities.
●
Removing the probe
1) Turn the power off.
2) Remove the probe by holding the connector and pulling it straight out.
Note: Do not pull the probe by holding and pulling the sensor cord.
Doing so could break the cord.
Measuring temperature
1) Press and hold the [Power] key for at least two seconds to turn on the power. The LED lamp and all
indicators light up for approximately one second to indicate that the measurement mode is established.
Note: The display of "– – – – –" appears in the channel to which no sensor is connected.
2) Press and hold the [Power] key for at least two seconds to turn off the power.
Attention!
- If the ambient temperature rapidly changes, the measurement accuracy may be affected.
Before starting measuring, allow the unit to adjust fully to the ambient temperature.
1. HOLD function
Use the HOLD function if there are large variations in measurement results during measurement.
●
Operation
1) Press the [HOLD] key in the measurement mode.
The
HOLD
character lights up to indicate that the measured value is held (frozen).
2) Press the [HOLD] key again to cancel.
The
HOLD
character goes off to indicate that the measurement mode is resumed.
2. MAX/MIN function
The unit can memorize the values measured since power-on, and display the maximum value (MAX) and
minimum value (MIN) among them.
●
Operation
Every time the [MAX/MIN] key is pressed in the measurement mode, the values of maximum, minimum
and measured of each channel are toggled in this order.
In addition, the
MAX
or
MIN
character lights up in the display.
Note: When the
T1 – T2
or REL function is used, the maximum or minimum value up to that time is
cleared and the new maximum or minimum value logged since the
T1 – T2
or
REL
function was
