MAX/MIN. This key calls up the peak and valley values
contained in memory. The first push recalls the maximum
value reached for the variable since the last reset operation
(peak) and activates the "MAX" LED.
The second push recalls the minimum value registered after
the last reset (valley) and activates the "MIN" LED.
A third push shows the Peak-Peak detected value since the
last reset or tare and activates the “MAX and MIN” LED.
A fourth push brings the meter to the normal reading.
The peak, valley and peak-peak values are updated even
when they are registered on the display.
To erase the peak, valley or peak-peak memories, press
"MAX/MIN" one, two or three times to display the value to
be reset. Press and hold down the "RESET" key and
simultaneously press "MAX/MIN". Release "MAX/MIN" then
"RESET".
When reseting the peak to peak value, automatically the
peak and valley value are reset, getting the actual variable
value.
RESET. The "RESET" key is used in conjunction with "TARE"
and "MAX/MIN" to erase the memories of tare and
peak/valley or peak-peak value respectively.
When a tare or a tare reset operation is performed, the peak
, valley and peak-peak are updated with the actual value.
PEAK = Maximum detected value since the last reset or
tare.
VALEY = Minimum detected value since the last reset or
tare.
PEAK-PEAK = Absolut value of PEAK and VALEY distance
value detected since the last reset or tare.

2.1 - Power supply
Should any hardware modification be performed, remove the
electronics from the case as shown in figure 9.1.
115/230 V AC: The instruments with 115/230 V AC power, are
shipped from the factory for 230 V AC (USA market 115 V AC),
see figure 9.2. To change supply voltage to 115 V AC, set
jumpers as indicated in figure 9.3 (see table 1). The wiring label
should be modified to match new setups.
24/48 V AC: The instruments with 24/48 V AC power supply,
are shipped from the factory for 24 V AC, see figure 9.3 To
change supply voltage to 48 V AC, set jumpers as indicated in
figure 9.2 (see table 1). The wiring label should be modified to
match new setups.
10-30V DC: The instruments for 10-30V DC power supply are
prepared to withstand any voltage between 10 and 30V without
need of wiring changes.
