1-2 Front Panel
Refer to Figure 1 and the following numbered steps to familiarize yourself with the meter's front panel controls and
connectors.

The upper display is for displaying the Stop Watch and MAX/MIN reading and has symbols for auto polarity, REC,
MAX, MIN, E, °C and °F.
The lower display is for displaying the reading measured and has symbols for auto polarity , HOLD, J, K, °C, °F,
(TI, T2 and T1-T2 for 55 only).
2. Thermocouple Connectors — Allows connections of miniature thermocouple plugs. (2 for Model 55).
3. Hold Switch — Used to hold the numeric reading on main display. When pressed the HOLD annunciator
is displayed. Conversions are made but the reading is not updated.
4. Power ON/OFF Switch — Turns the thermometer on or off.
5. Key — This key is used to control the timer. The timer is only enabled while the minor display is blanked.
(The maximum reading is 99:99). When the first press is made, the is displayed and the timer starts
