Up & Down-
In the pH/ORP
measure
mode, these two keys
are used to manually enter the temperature
values. They have no effect on the unit when
operating in ATC mode.
In the ORP calibration mode, these two keys
are used to adjust the RmV display value.
In the “Recall” mode, view saved data and data
storage site number by pressing these keys.
In the “Delete ALL” mode, select between the
“Yes” and “No” for data all delete.
In the “Delete One” mode, view to be deleted

OPERATIONAL PROCEDURES
A. pH Buffer Set Selection
The 6177M/6177EU meter has two buffer sets: 1.68, 7.00,
4.01, 10.01, 12.46 pH and 1.68, 6.86, 4.00, 9.18, 12.46 pH.
To change the buffer set, turn off the unit, then press and hold
the
“Stand”
key while turning on the unit again.
[
Note:
There is no need to repeat this procedure every time
the unit is power up unless one decides to change the buffer
settings.]
B. pH Calibration
The 6177M/6177EU uses up to 5 point calibration.
[
Note:
If the device is required to perform more than one
calibration points, the first calibration point must be 6.86/7.00
pH.]
a. Calibration with an ATC/Temp probe in the pH-AUTOLOCK
mode.
1.
Turn the unit on. In pH mode, press
“Clear”
key for 5
seconds, all LCD elements will lit up. The meter clears all
calibration values stored in internal memory.
2.
Connect the pH electrode to the BNC connector and the
ATC/Temp probe to the ATC/Temp connector of the unit.
