Interface

The unit has a primary (larger) display, and a secondary (smaller) display.
"Mode" button switches between pH, mV, RmV and temperature modes.
The "measure" button is used to take a reading only if the meter is configured to operate in AUTO mode (where it will hold the last measurement on the screen after it stabilizes).
- It is also used as an escape key. It can be used to exit the setup menu or abort a calibration.

CONF Config (Select measurement resolution and buffer set)
- RES Resolution can be 0.1 or 0.01
- CAL Auto or Manual calibration. If auto, then goto BUF submenu (which is part of the same Conf menu).
- BUF Sets type of buffer set when in autocal mode. USA is (pH of 4,7,10) whereas DIN buffers are (pH of 4,6.86,9.18).
GEN (Auto Meter Shutoff)
TEMP (Select temperature units and temp used for compensation)
- UNIT can be DEGC or DEGF
- DEGx sets the manual compensation value
- READ can be set to either AUTO or continous. In auto mode, hit the "measure" button and the meter will wait for the value to stablize, lock, and hold that measurement on the screen. Continuous mode constantly updates and requires no button presses.
LOG (Datalog on/off and clear)
- DATA (logging) can be either on or off.
- DEL can be either NO, LAST (only last reading), or ALL (delete all data)
CAL (Allows review and clearing of calibration data)
- SLP.1 SLP.2 and SLP.A may be present in the submenu, however, SLP.2 and SLP.A will only be present if 3-point cal is used.
- BUF.1 BUF.2 and BUF.3 may be present in the submenu, however, if there was only one calibrated value, BUF.2 and BUF.3 will not show.
RST (Factory Reset)

Calibrated by pzieba on 12/11/21 with a 4 7 10 pH set.
- Slope value was found to be SLP.1 was 99.2 SLP.2 was 99.0 and SLP.A was 99.2
