[. . . ] The values may be recalled or HI LO cleared at any time during the measurement. Check the highest or lowest HI LO measured temperature by pressing the respective HI or LO key button. The appropriHI ate display indicator, "HI" or "LO", will be displayed together with the value retrieved from memory. Release the key to resume the normal operation. 10 The alarm is triggered when the measured value is greater than the high set point or lower than the low set point. In such an instance, the corresponding graphics indicator blinks accompanied by a sound. The buzzer may be turned off by pressing any key except the ON/OFF key (by pressing ON/ OFF the alarm is disactivated and the scale changes). by pressing ENABLE key (note that the set point values will not be affected by this action). To set the alarm limits, press the SET key on the front panel. SET 11 The flashing "HI ·))" and "LO ·))" HI ·)) alarm indicators request the LO ·)) user to opt for the set mode. Select the HI key to enter the HI LO set mode for high temperature point or the LO key for the low temperature limit. If the HI key HI is chosen, the low alarm indicator is switched off and the "HI" indicator appears in the top right corner of the LCD. Exit from the high alarm limit setting by pressing the SET SET key for a second time. The user may now proceed to set the low alarm limit or return to the measurement mode by pressing the SET key again. The setting of low temperature limit works in a similar manner. The next memory function key, MR/M, serves two purposes: MR - The first entry (by pressing M this key once) enables the recall of the previously stored temperature reading. In this mode of operation, the display indicator "M" M is kept static. - The "M" display (by pressing MR/M twice) indicates the M constant updated discrepancy between the memory content and the measured value in a continuous measuring process. Calculation is performed by subtracting the measured value from the memory content, i. e. : M = (M-T) where M = memory content T = measured temperature A negative result therefore represents a lower memory value. By pressing the MR/M key once again, the user exits from the memory mode. MR M MEMORY MODE (HI 9053 and HI 9055 only) There are two modes of operation. The first is the memory & hold function which is activated by MEM HOLD the MEM HOLD key. The measured temperature is captured into memory and frozen on the display when this function key is pressed. The memory content will be overridden each time the memory & hold function is activated. [. . . ] Operation of these instruments in residential area could cause unacceptable interferences to radio and TV equipments, requiring the operator to take all necessary steps to correct interferences. Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance. To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24VAC or 60 VDC. To avoid damages or burns, do not perform any measurement in microwave ovens.
