Contact measurement with a type-K probe

In addition to the non-contact infrared measurement feature, the Testboy
TV 325 is equipped with a type-K probe for performing contact measure-
ments. In order to make contact measurements, connect a standard com-
mercially-available type-K probe with a standardized mini-plug into the ap-
propriate socket on the instrument.
Use the MODE key to select the "PRB" function. The temperature value from
the type-K probe will then be shown in the lower display row.

Alarm function

Use the MODE key to select the value that you wish to set for the alarm
value. "HAL" for the upper alarm value (high alarm) or "LAL" for the lower
alarm value (low alarm). Use the two arrow keys to set the required value.
The instrument issues an optical and audible alarm if a non-contact meas-
urement falls below or above these alarm values. The display then shows
the alarm symbols "Hi" or "Low".
