Thank you for choosing an HK Instruments MM Series liquid col-
umn manometer. The MM Series is intended for use in commercial
environments for air and non-corrosive gases. The MM Series is
designed with overpressure reservoir to protect the manometer
liquid from leaking into the duct during over pressure.
The MM Series includes a field adjustable zero point calibration
and pressure limit stickers. The MM Series is available with op-
tional level bubble and NIST standard calibration certificates.

2) Unscrew the zero adjustment knob (lower one) so that it is com-
pletely open and then turn one round backwards. Open the fill plug
(upper one) and pour in the gauge fluid until it reaches the zero on
the scale. Finetune with the zero adjustment knob until the fluid is
exactly at the zero level. Screw the fill plug back to its place.
3) Connect the pressure tubes. Connect positive pressure to port
labeled “+” and negative pressure to port “-”.
NOTE! Only use gauge fluid approved by HK Instruments to guaran-
tee accuracy and functionality of the device.
