Changing The Displayed Temperature Units; Orp Operation; Data Hold; 15-Reading Measurement Storage - Extech Instruments ExStik PH100 User Manual

Changing the Displayed Temperature Units

Press and hold the CAL button for approx. 3 seconds. The
then the numerical temperature value will change after the button is released. If the
Calibration mode is accidentally accessed ('CAL' appears on the LCD) simply turn the
TM

When an ORP electrode is connected and the ExStik
Calibration mode. 'SELF' and 'CAL' will appear on the LCD while calibration is in progress.
After the calibration is complete, 'SELF' and 'CAL' will extinguish and both the main display
and bargraph will read ORP in mV units. The bargraph reads 0mV (far left), 500mV (center),
and 1000mV (far right).

Data Hold

Press the MODE button to freeze the current reading. The HOLD display icon will appear
along with the held reading. The held reading will be stored in the next 15-reading storage
location (see below). Press the MODE key to return to normal operation.

15-Reading Measurement Storage

1. Press the MODE button to store the current reading (Data Hold will activate). Press
MODE again to return to normal operation. Repeat step 1 above to store the next
reading and so on.
2. If an attempt is made to store more than 15 readings, the stored readings (starting with
the first reading) will be overwritten.

Recalling Stored Readings

Note: First ensure that the HOLD symbol is not displayed. If it is, exit the HOLD function by
pressing the MODE button.
1. Press the CAL button once and then press the MODE button immediately after CAL is
displayed; the location number (1 through 15) will flash. If the CAL mode is accidentally
accessed (display flashing), press the CAL button again to exit.
2. The last stored reading taken will be displayed first. To advance through the stored
readings, press the MODE button. The location number is displayed first, followed by the

will turn off when the pH electrode is recalibrated.

RENEW Display

A flashing 'RENEW' warning indicates that the probe may be nearing the end of its useful
life. If cleaning or recalibration does not cause the RENEW icon to disappear, replace the
probe (see optional accessories below). The RENEW display appears as a result of the pH
electrode slope falling below 75% of a nominal slope.
